Review summary

Created with AI, based on recent reviews

Evaluating 62 reviews, most reviewers were let down by their experience overall. Customers frequently struggle to reach anyone for assistance due to extremely long waiting times, automated phone menus, and constantly dropped calls. People find the customer service thoroughly unhelpful, with staff members often failing to resolve basic problems, communicate internally, or follow up as promised. However, some customers also noted unexpected extra charges, recurring billing errors, and issues with billing after contracts officially ended. Consumers additionally experienced frustrating network outages that left businesses completely without mobile or broadband service for consecutive weeks without proper technical support.

For the sake of you business and sanity...AVOID

I left a review on the 10th November regarding my experience of o2 Business. The company responded and asked for further details which I provided. I also provided very specific information on emails I had sent/received, highlighted my experience (again) and made them aware (again) of the health implications to my son of them inexplicably cutting my phone off but guess what?

Silence. Nothing.

For the sake of your business, sanity and your precious time DO NOT take a business package with this company. Go anywhere else, pay more if you have to but avoid them at all costs.

Shortly a response from the company will appear below this review. They will ask for further details so they can look into this further but this merry-go-round won't be starting again. I'm done.

Unusable 4G/5G

Their signal is weak pretty much everywhere (across most of Nottinghamshire/Derbyshire) and don't get me started on the non existent 4G/5G. We cancelled the contracts after a week as my phone was unusable unless you were on WIFI.

Then to make matters worse, when I rang to cancel and set up returning the phones, I was told they would not release the PAC codes until they had received the phones first which would be about a week after we returned posted them back. So I have to try and run a business without a mobile phone for a week.

Hi Oliver,

We’re sorry you had a poor experience with O2 Business.

We’d love to get to the bottom of this and help you get it sorted, but to do that we’ll need a few more details.

We’ve requested some more information through Trustpilot. If you can respond to that when you have a moment we’ll look into this ASAP.

Thank you,

Worst customer service I have ever…

Worst customer service I have ever experienced. Can’t speak to anyone who has any experience. Everything is so scripted that it sounds like AI and they just do not know what they are doing. 2 weeks to get an e-sim. The shops say they don’t deal with business queries. Walked in to EE shop next door and they sorted it all out. You have lost over £3k a year of business from me and I will never go back!!

Prices for our business lines have all increased a minimum of 15% but the network signal seems to have got worse. Also just tried to cancel one member of staffs contract that expires in 4 weeks and it took 1 hour and 3 people on the phone to help. Very hard to understand what they was saying, sounded like they was working out of a public toilet somewhere with the background noise, all our contracts will be cancelled and moved. From one of the best networks, to one of the worst in the last 12 months.

If i could give zero stars I would.
We've had a business account for 8 years and used to have a great account manager who made managing our account and ordering new phones super easy.
Unfortunately several changes later its now IMPOSSIBLE to speak to someone, the few times i do get through it takes in excess of 2 hours to speak to someone and the customer service is painful at best.
Its impossible to do anything on the website without it crashing or not finding the page.
I cant even cancel the contracts because i cant get in touch with them. Probably the worst service i've ever received from a company>

I use 02 with Kynex and the below is my experience.
Fraud .
they sold me a transfer from my service provider to another to save me money and they would take care of the “contract buy out” it took 10months for this over 2 years ago . They then claimed never to receive my device leaving me owing 800 pound to my old provider. Which I never received . The company had been sent a police references number . Still ignored and no money received they continue to lie stating they hasn’t received my old device . This was on going and never resolved at the time my father passed away and I couldn’t continue the battle that they made impossible with this . I become fed up of repeating my self .i was contacted again by them to purchase. 4g box which seemed great and fair . 4 months later this didn’t arrive I spoke to several people I was then offered to cancel this but I still have to pay upfront to get my money back ten days later the next month . This doesn’t happen with out me chasing or the figure being wrong . I have spent hours on the phone and owed over 175 however you just can’t communicate this or get them to understand . I upgraded my phone on the 7th October and still not received the device this is now coming up to the 30 day period
I had 4 weeks with no services and had to pay the full bill .
I have notified my invoice is wrong you only get the response “ I tried to call you today “
They can not correct or work out this concern you often get a giggling individual.I would urge anyone thinking of using them to reconsider !!!!!
I have wasted so much time and frustration with this company and always given them the bennifit of the doubt . They have negatively affected my clients and mental health . There promises never come off . I have withdrawn legal action time and time again with huge regret . I have been more than fair and understating with this company . There are staff who I feel try to resolve concerns but hands are tied .

Just the most dreadful customer service, in all respects. Help only available 9-6pm Mon to Friday, and even if you can get through to someone, the line quality is so bad I might as well try having a conversation with my dog. Cancelling my contract and switiching to another company asap.

O2 Business Shambles...

Across the past few months I have been attempting to achieve what ought to have been a seamless change from a personal O2 account to a business account.

Not only has it been THE most poorly executed change of service (in a single business) that I have ever experienced, the pain continues.

I have had zero communication with anyone that appears to know what to do, I was without a phone service on my business phone - my only form of communication- for nearly 2 weeks (at some cost to the business!), I am not receiving monthly bills (needed for proper accounting purposes) and I am currently on the phone to customer services being told I have failed security - having given my mobile number, my name and my company's name - the only significant pieces of information required and on record!

Really O2 - get your act together .... it ought not to be this difficult to care about your customers!!

Crap Customer Services

Why big companies like O2 Business and Virgin Media have the worst Customer Services ever.
Hours of phone calls with customer services and after 6 days issues not yet resolved. Some of the agents also have language and training issues

REFUSING TO GIVE MONEY BACK!

After my contract finished I was told I had £135 in credit.

After 4 telephone calls lasting on average 30 minutes and at least 4 emails to the complaints team no one has got back to me.

Apparently a cheque was sent in July it's now the end of September still no contact or cheque.

I can't believe a big company like O2 can basically steal from it's customers.

if I could rate a 0 I would AVOID AT ALL COST.
been with o2 business a while now phone randomly got barred even though the bills where up to date they couldn't reactivate my sim as apparently it is all working. when I finally got them to listen eventually they sent 3 different sim cards and E sims non of which activated. after 3 months of using partners phone to try sort this out and loosing job interviews in the process it worked but they refuse to acknowledge fault. any reimbursement I was told to contact crown communications who say they only deal with setting up contracts and not providing the services and that I should talk to o2 who say its not their contract and to contact o2 business who say its not their fault and to contact crown communication who say its not their fault call o2...….etc!!!!
now stuck in a contract till 2026 and cannot wait to leave and If you want something decent look elsewhere.
absolutely abhorrent.

DO NOT use O2 Business

DO NOT use O2 Business!

I have had an O2 Business account for around 1 year now, and in that entire time I have not been able to access 'My O2' business account online in order to manage and view my bills etc.
I have been on to and chasing O2 for this entire year and still there has been no resolution. Their customer service, despite them trying their hardest, seem incapable of achieving anything meaninful, and the tech team never follow up as promised. On the whole, a useless company with even worse customer-relations

They set up my Direct Debit incorrectly and failed to take any payments. When I noticed, I called them and paid the outstanding balance directly. Two weeks later, they suddenly withdrew £1,720 from my account without warning.

After countless phone calls, broken promises, and zero resolution, I can confidently say their customer service is some of the worst I’ve ever experienced.

Do yourself a favour—go elsewhere.

Its hard to run a business with O2 Business as you spend so much time on the phone trying to sort out the most basic of problems.

After 3 years I still cannot get access to my account or download (or even receive) invoices. Appalling service.

To try and resolve it will be require a min 45 min call with a polite but ultimately useless rep in the Philippines - which I simply dont have time for. This is after spending hours trying to resolve the issue with them over the past few weeks.

I finally ditched O2 after 20 years

I have been a business customer with them since around 2007. Deal was good some handsets on deals then in 2018 decided to consider sim only. Rates were decent about 25 quid a month for 2 sims unlimited calls and text 10G of data... nothing to complain about apart perhaps the ever woefully inadequate "flash" interface in the mid 10's (finally ditched thank god). Then somewhat decent billing reports as of late. Only I never have been sold on their website and support chat was passable. Somewhat helpful customer service depending on who you got to talk to. Last contract renewal was going to double my costs so I voted with my feet and moved to Lebara. Same service (actually better) for less. Also did not fancy having to go through hoops telling O2 I changed my business name. Talking about rewarding a 20years long customer. I guess they got their money worth. Not to mention the EASY way to manage your numbers on Lebara's website customer portal.

So long. Good luck with Virgin

Zero customer service

I have tried for more than hour to contact O2 business by phone and online chat. No result whatsoever. Have had five numbers with them for several years but it's time to move on.

O2 Business/ Airtime Solutions

O2 Business/ Airtime Solutions, two Complete corrupt companies, mis selling/ misrepresenting contracts, charge extra fees for services you've not received, customer services have one line, you still have to pay, phone blocking for none payment of services you are not receiving, then expect you to pay the balance on a contract after they have blocked your company phones,due to their billing errors. Complete useless shite company, not to mention, masts always down for repair, a failing service. Do yourself a favour and stay away from this shamble of a company, who do nothing to sort their own problems out, just threaten debt collectors and legal action for their mistakes. I can't tell you how shit this company is, theft, theft, theft is all they know.
