what is your question now?

Is this even legit ? Like I would have switched to a competition if not for the extra 10 gb they promised .

I wasn't there for the phone call, so I can't comment on your descriptions. If things were discussed differently than they are implemented, you have a legal right of withdrawal.

Yes but the phone call was recorded , you can listen and implement it ?

Anyways , the entire thing was a bit awkward for me , as you can imagine 

Request the voice recording if o2 gets in the way and get legal advice, either from the consumer advice center or a lawyer.

Hi ​@Hannan95 

welcome to our community. Nice to meet you. 

I’m sorry to hear that there was a misunderstanding concerning the new tariff. Did you keep your old plan and just got an offer about a discount and additional the so called “Datengeschenk” or did you decice to change to a complete new tariff? 

If you are still within the 14 days after signing the contract extention you can withdraw the contract. Afterwards this is no longer possible. 

Thanks to Bumer for assistance.

At the time I was using O2 for 2 years, so I kept my original plan and extended for 1 more year because I thought I would get more data :/
