O2 is simply a scam
O2 is simply a scam. End to end. Their contracts are shady, badly explained and probably illegal to some extent.
Speaking to them is very hard, when you manage, 80% of the customer support has no idea of what’s going on, so you often receive wrong advise.
What can I add, PLEASE don’t give any money to these scammers.

Hello Guglielmo, thank you for contacting us on Trustpilot. I’m sorry to hear that you’re not satisfied — that doesn’t sound like a good experience. Unfortunately, without the exact details, I can’t assess what exactly happened, but I’d be happy if you could reach out to our customer service team or the o2 Community: https://www.o2online.de/kontakt/
