About Gamma

Written by the company

Gamma is a leading provider of Unified Communications as a Service (UCaaS) into the UK, Dutch, Spanish and German business markets, supplying communication solutions directly and via our extensive network of trusted channel partners.

Of course, sometimes customers may need to reach out due to any issues they may have experienced - we encourage customers to contact us to resolve these issues promptly. Please click the link at the bottom to raise a general complaint about our products or services, and we will be happy to look into it.

Regarding scams and nuisance calls, we are Ofcom registered, fully compliant with regulations and we take the misuse of our numbers very seriously. Gamma is a business-to-business (B2B) wholesaler for number ranges to thousands of businesses across Europe. Therefore, it can appear that Gamma is making calls to the general public or able to control who uses them - this is not the case. Our numbers are being, at times, misused by other businesses, or non-Gamma numbers are ‘spoofed’ to make it appear as though Gamma is calling when this is not the case.

With that being said, we want to help clamp down on nuisance calls in any way we can. Therefore, we would be happy to investigate any reports to check the current owner of the numbers and can act where applicable if they are ours. Instead of leaving reviews, we would kindly ask that you provide the details of the numbers that have called you, including timestamps with our Misuse team. It helps to provide the number that received the call so we would ask that you complete the form via the link at the bottom. Our Misuse and Fraud teams can then investigate the situation.

However, if you do not want to contact us further, we would suggest reporting the numbers to the police, via www.actionfraud.police.uk or call 0300 123 2040 (if in England, Wales or Northern Ireland). If in Scotland, report to Police Scotland by calling 101.

Collaborate app issues - No answer from Gamma

No answers to their phone/ reception, ironic as I'm calling to ask why the collaborate app doesn't allow us to answer calls. The phone rings but you can't pick up the call...really frustrating and detrimental to business relationships.

Very dodgy underhand sales tactics

Very dodgy underhand sales tactics, ring and claiming it was a follow up call to a matter we've previously discussed. Just lies and complete fabrication, be aware, this is how this company operates!

We are carrying out legacy updates to previous complaints. Thank you for your communication regarding contact from a number allegedly linked to Gamma. We want to clarify that Gamma, a wholesale telecommunications network, is not making these calls. We will investigate any breaches by our customers.

However, we are seeing a huge surge in scam call centres 'spoofing' Gamma's numbers to mislead recipients, making it hard to track the source. This means that they are using non-Gamma numbers and hiding their identity by faking it to appear as Gamma.

We encourage you to register your numbers with the Telephone Preference Service to avoid unsolicited calls.

If you receive unwanted calls, you have options based on the type of call:
1. For "Silent and Abandoned Calls," contact Ofcom at 0300 123 3333.
2. For "Sales and Marketing" calls despite being registered with TPS, reach out to the Information Commissioner at 0303 123 113.

Both organisations can assist you with your complaint. If you’d like to discuss this further, please contact us at Misuse@gamma.co.uk with relevant details.

We hope this context helps you going forward,

Kind regards

Scam central...literally.

Called me this morning to check if my phone was active. Literally the first step to setting up a scam. I gave the number a Google which led me to Gamma Telecom Holdings Ltd.

Yet another "telecom" company supplying criminals and scumbags with our precious contact details but what bothers me the most is that I've had a new number and have rarely given it out to anyone! Who gave (sorry, SOLD) them my details?

If I get another dead call from them I will take it as hostile activity and will be reporting you as far as I can.

CS has unidentified number of "right teams"

Trying to reach CS is impossible. When you call their CS number you'll go through initial "Hi, please select 1 or 2" auto attendee menu. Initial waiting time wasn't terrible so I got to FIRST "adviser" who asked me for details. I was then informed that first adviser has to transfer my call to the RIGHT department so I landed in queue void for 10 mins (including initial first 10 mins reaching them = 20 in total). Salvation is here! SECOND "adviser" finally logs my call but AGAIN asks me for my details + ISP login details. Guess what? SECOND adviser was not the right team... So they transferred me over to "the right team". I am in this queue void where you send people that you don't want to talk to and it's been now 12 minutes (in total 30+ mins). For past 12 minutes I heard "Thanks, we will now PLACE you in the queue". I will just highlight that I was calling on behalf of mutual customer. If I was their direct customer and my broadband was down due to line issue and I would have to go through this QUEUE VOID I would immediately terminate my contract with them...

UPDATE:

After 47 mins in queue (checked time on my handset) my call just got disconnected. Since then Gamma did not even try to call back.

Horrible

UK BASED SCAM COMPANY?

I keep getting cold calls or or someone who knows my name and tries to convince me my house needs repairs. The latest number came up as Sheffield 01144783876.

I cannot understand how Gamma can allow a phone scamming company to operate under it. Even the Gamma website looks dodgy.

Cold Caller - Vaguely Answer Direct Questions

Received a cold call from this company to my business (nothing unusual there). One of my first questions: "Before we continue, is this a sales call?", "We can't sell you something you already have", "Is that a yes or a no?", "We are looking at updating your contract", "You are answering a simple question with a very vague answer, please remove me from your call list, bye". Blocked the number after repeated attempts to call me back.

Dear Susan. We are sorry to hear about your experience. Gamma is an Ofcom registered range holder for telephone numbers for thousands of businesses across the UK. We take the misuse of those numbers very seriously. If you would work with us to investigate this further, we would appreciate it – please contact us directly and we can pass any misuse on to our Fraud team.

UPDATE - We are conducting legacy updates to the previous complaints and we apologise for not providing you this at the time. We want to clarify that Gamma, a wholesale telecommunications network, is not making these calls.

We will investigate any breaches by our customers. Unfortunately, we are also seeing a surge in call centres 'spoofing' Gamma's numbers to mislead recipients, making it hard to track the source. This means in those cases that non-Gamma numbers are being used to commit acts of fraud, while faked to appear as one of our numbers.

We encourage you to register your numbers with the Telephone Preference Service to avoid unsolicited calls.

If you receive unwanted calls, you have options based on the type of call:
1. For "Silent and Abandoned Calls," contact Ofcom at 0300 123 3333.
2. For "Sales and Marketing" calls despite being registered with TPS, reach out to the Information Commissioner at 0303 123 113.

Both organisations can assist you with your complaint. If you’d like to discuss this further, please contact us at Misuse@gamma.co.uk with relevant details.

Failing the above options, we would recommend alerting the police (if in England, Wales or Northern Ireland, visit www.actionfraud.police.uk or call 0300 123 2040. If in Scotland, report to Police Scotland by calling 101).

We hope this context helps you going forward,

Kind regards

Gamma the scammer?

Gamma the scammer?

I’ve now had several calls from numbers attributed to this company. Each time I lift up the phone there is no answer from the other end. Why are they doing this? Presumably they’re trying to find out if I answer and pass this info on. Also if I don’t answer they can work out when no one is at home. Either way this info is useful to scammers in particular

Awful is being unkind to the word…

Awful is being unkind to the word awful!
There was a failure to delivery services across a three-month period starting from November 2020 to February 2021. Gamma completely failed the redirecting of our phone lines and despite dozens of calls failed to rectify the fault over this period.
I spent a considerable amount of time and energy calling to try and rectify for it not to be rectified.
The issues caused a substantial loss of revenue, in a peak period time of sales for the studio when we usually sell a considerable amount of Christmas voucher campaigns including Christmas gifts for recording studio experiences and singing lessons.
Further loss of potential sales due to a lack in confidence in the phone services prevented us from launching further marketing and advertising campaigns.

I had a terrible experience with Gamma

I had a terrible experience with Gamma, I signed up to be a partner to sell network 3, so many hidden costs and things were unclear upon sign up. I have been in telecoms for 13 years and will be telling all my connections about the way I have been treated. **** is not a credit to Gamma and has provided me terrible service.
