Hello @Zeynepm
Where did you signed the contract? In a Shop, online or Hotline?
Hello @Zeynepm,
welcome to our o2 Community. 
It's not great to read that you want to get out of the contract quickly. What is the reason why you're not happy with the contract?
Bollermann's question would also be interesting. How did you conclude the contract?
How exactly have you already tried to revoke the contract?
Kind regards, Lea
Because first I ordered a wrong tarrife and after that I ordered a new sim-card with the tarrife I wished to have and I am happy with it.
but the first sim-card with wrong tarrife I want it to be cancel, because I don’t use it and don’t need it.
I signed it online and contacted with o2 team by email.
I UNDERSTAND it is my bad, but I believe there is always a way. but o2 team is keep telling me there is no way, in Germany when you signed a contract you should wait until its done.
Yes, there is (was) a way: send a notice of revocation to widerruf@cc.o2online.de within 2 weeks. You say you sent emails, but to which address?
What you are being told us correct. And not just in Germany.
Directly o2 online?
When you didn't send an e-mail to widerruf@cc.o2online.de weithin 14 days, there"s no way. or to which e-mail adress you've contact o2?
@bs0 Oh then it means I sent to a wrong email!
Yes, and that is not an address for o2 customer services.
Do you maybe know somebody who would be interested in taking over the contract you no longer want?
Unfortunately no. It! seems I made a big mistake and have to wait until it finished (2 years) costs alot
♀️
thanks alot everyone for making it clear for me 
@bs0 vllt kann man ja hier noch was machen.. auch wenn die falsche e-mail Adresse genutzt wurde...
@Zeynepm
Which discount (name) is for the 2nd new contract?
@Bollermann
you mean this? :
02 Mobile Unl. On Demand Online
(2024)
@Bollermann Wenn die E-Mail doch bei der Kundenbetreuung gelandet ist, ja. Sie müsste dann die Moderation sehen können.
@Zeynepm Not the tariff. Name of the discount (Rabatt)
Hello @Zeynepm ,
Please excuse the long wait.
I've had a look and spoken to my colleagues. The revocation arrived here on the last day of the revocation period,
albeit to the wrong email address. We will therefore deactivate the contract tomorrow and you will then receive
a credit note for the costs incurred. You will then see this on your next bill.
Best regards,
Maria
@o2_Maria
OMG :’) thank you so so much for your help and support.
Hello @Zeynepm ,
I was very happy to do that.
After all, we are here to help when we have the opportunity. 
Best regards,
Maria
Hello @Zeynepm ,
I looked at your new bill today. Since the contract was only deactivated on January 28, 2025,
this contract was still charged pro rata on the current bill.
I have credited this amount back here straight away.
Best regards,
Maria
Hello @Zeynepm
I looked at the new invoice today and, as expected, a small part of the contract was still charged.
I have now had this amount credited. You will then see this again on the next bill.
Feel free to contact me here in the community at any time if you have any questions.
Best regards,
Maria
Hello @Zeynepm ,
A few days have now passed and I just wanted to ask whether you have already received confirmation of the credit note?
Are you happy with your contract?
Feel free to get in touch here in the community if you have any questions.
