Ratings and reviews

I got scammed on false promises on a cell data contract where I ended up paying 250% of the promised price. I was reassured on the call that I understood everything correctly about the contract. When I noticed I was paying too much, I was told it's my fault for not noticing this in their email. I've also been waiting on my fiber Internet connection that has been available in my house for about half a year now and they never know what's going on. Very unprofessional.

Aaand they fixed the issue, now I can install the app from Google Play again. Yay! 🎉

Update 31.03.2025: I was transferred to the new 1&1 5G network and I have almost no network (phone, Internet). Support can't help me either. ___ 1&1 seems to ve very complicated. I wanted to transfer my esim from my Pixel 7 to my Pixel 8 Pro, and the Pixel has this option, but it is not supported for 1&1 esims. Now I've had to order a new QR Code through the portal that will be sent by post. Which year are we in? This is definitely not 2023, this is a very bad user experience.
