yallo Reviews 

I have numerous examples of MAJOR the security isssues and vulnarabilitiee of yallo customer portal and general customer service practices. SUPER INSECURE.
When I tried complaining to the customer care - I was ignored (chat, call, info at yallo.ch).

Where do I go next? I have an active fraud going on my account (session hijacking), but after spending hours on the support calls and chats I am getting nowhere. Just every time I contact I am promised a call back and that that the case has been escalated. So what do I do?

If you want to have problems and waste your time calling customer support this is your company. Do not hesitate to sign up for one of their plans to get lots of frustration and dissatisfaction.

If you have an enemy in life, I would sign them up, you will ruin their days.

Shockingly bad customer service when trying to cancel.
They can sign you up online no problem, but to cancel, you need to speak to a human 'to provide you best customer experience'.
Getting hold of a human is a nightmare, particularly if you don't have international calling. The provided chat bot never has any human monitoring, and claims to create tickets which are never answered.
Got stung with a data bill when crossing over to Germany despite not even using the phone, the device's background tasks (not downloading anything) were sufficient to incur 20CHF.
Giving 2 stars because the call quality was fine.

I spent my whole morning trying to have a contact with an agent on chat but it was not possible. They told me they forwarded me to some human agents but nobody answered.
No support at yallo.
Bye bye

They never respond to plan cancellation requests even if you contact them to the channel they require for this purpose. I’ve now been trying to contact them for weeks and nobody ever comes back to me. The standard support just keeps asking me to try the right channel again and again. So it looks like you could just as well be paying forever

Zero!
No calls returned
No emails returned for weeks
Very bad customer service!!!

I signed recently a monthly 4G mobile Internet subscription at CHF 39.- with a discount of CHF 30.- and it is clearly indicated on my contract that the rate to be paid is CHF 9.-. First scam, I receive invoices of CHF 10.- per month. At this stage, I did not want to nbother about the unjustified 1 Swiss franc if only the service was correct.
To my great disappointment, the internet connection is around a few hundred KBPS and often less than 100 KPBS!

Cherry on the cake, the hotline number is chargeable and they have an awful contact center.

IF ONLY I HAD KNOWN. Terrible company. Avoid at any cost. Make pictures of every document you see as the contract they send you is not what you ordered. Beware of their billing. Contract clearly shows free ebill when they charge you CHF 4 for paperless bill. They did not apply the promotion they were offering.

Best prices.
- Mobile Top
- Internet Max Fiber Top - But unfortunately, Zyxel Router Trash

Nevertheless Top Company; unbeatable prices and good performance.

Never and never again.
Mobile internet even with activated 5G absolute trash. Very slow outside of city. In some cities doesn’t work at all even if you see all bars of coverage.
Terrible quality of mobile internet. Running away from Yallo to other provider.
Home internet - total zero quality service. Cancelled contract with my previous provider. Yallo did change activation to middle of August!!!!!!!!! This is not acceptable at all. If no internet today - all the best Yallo.
Never and never again to Yallo.
Terrible

Horrible experience with Yallo!
Made a new contract because last year paid 3 times more of extra cost due to international data & call charges. Changed the contract with Super Fat XXL to have all inclusive abroad. Ended up not being able to use data (that is included on the plan) in France. Called tech support, and didnt sort the issue. No solution for this issue.its unknown why I cannot use data, since my phone is working properly and all software updated.
Now, I have a extra bills to pay of the calls to the tech support!!! Its not an honest service and honest company.
Waste of money and resources.

Absolutely terrible customer service, unfriendly, unpolite and aggressive.
Need to ask information about an overcharge of 1 CHF and needed to pay 1.50 CHF for the call. This is just absurd.

This is the worst company. They will scam you on the invoices they send you and then send additional invoices with more fees. The phone support was rude and non-helpful. Stay away, it is an amateur circus.

Basically no support, you can write with a bot and if you ask for a human no one will connect.
Be careful with activation fees and minimum runtime of the contract, it is well hidden.

They are the worst scammer l have even see. Activation fee!! I was never told and because of the language, they took advantage and l paid 99fr. Becareful with them.

Didn’t send me the contract in the first place, turned out I had to give months of notice in advance for deactivation of the service. I asked for the contract and I checked and in my case I didn’t have to give any notice.
I call back customer service and the say in a rude way that it was not true I had that right (they just said NO to everything I was saying without any argumentation or evidence) and that anyway they had already registred the end of contract with those months included to be paid

Even i can’t give o star so bad service every month our bill increases i don’t know why then we need to talk more than 10 minits to explain don’t choose this ….

Signed up with the promise that the price would never increase for a 'lifetime', and would remain the same 'forever'. After 3 months, I already get informed that the price is increasing by 1 CHF per month.

When I called and complained the staff said 'its only 1 CHF' missing the point that 3 months is not a lifetime or forever. Terrible. Crooks breaking contract law.

I have been a client by yallo with 2 numbers and a TV/internet at home. They cheat or make errors in monthly invoices regularly adding up some cost or applying a lower life time promotion than offered initially.

They overcharge in a monthly basis. I reach out to customer service, which I have to pay 1.50 to do so, and they refund me 6 francs. But every month is the same. They're the worst phone carrier in Switzerland. Don't be fooled by their low prices.
