Hello @cemalonur,
welcome to the o2 Community! Thank you for your enquiry here with us.
Regarding your request: you have concluded a new contract and now want to cancel it? Or did you actually mean that you wanted to cancel the contract? Termination means at the normal end of the contract term. So if you have a 24-month contract, the termination is registered at the end of the contract after 24 months. Revocation (in German: Widerruf - another word in English is withdrawal) is the 14-day cancellation period after conclusion of the contract (for online and telephone contract changes).
Cancellations are not processed by mail. Revocations, however, can be submitted by mail to the mail address widerruf@cc.o2online.de within 14 days.
If you concluded your contract on 28 January, the cancellation should have been received by 11 February. Is this the case?
Furthermore, if there are still problems with the sim card, we can also look into the problem for you. Unfortunately, your forum account is not linked to your phone number. But we have the possibility to get you into the private messages for data exchange. Please let us know how we proceed. 
Kind regards

Hi,
I concluded my contract on 28 January, but I cancelled the contract via phone on 07.02.2022 and created a new contract via phone. I signed the new contract on 07.02.2022. So, I have the right to cancel it till 21.02.2022 according to the revocation law. I want to cancel the new order and I have already sent the cancellation form to you. Could you please check and finalize the cancellation process and get me informed?
Phone number: 0176xxxxx518
Best regards,
Baris Cemal Onur

Hello,
I learned that it is not possible to cancel my postpaid contract. This is the history of my SIM-card order.
- 28.01.2022 → contract start date
- 07.02.2022 → I did not receive my SIM card. I called customer care services. They created a new SIM card order. They said your SIM card shipment seems lost!
- 14.02.2022 → I did not receive my SIM card. I called customer care services again. They said “you will receive your SIM card in the few days”.
I have been waiting for a SIM card for more than 17 days. I am really wondering when I am going to receive the SIM card? In addition, I cannot see my postpaid contract details on the Mein O2 account page. In summary, please share the tracking number for the SIM card and please connect my postpaid contract to my O2 account.
Best regards,

Hello,
I received that my SIM card will be coming in the next few days via deutsche post but there is no tracking number. I cannot see my SIM card order in the https://g.o2.de/bestellungen/ Orders section. Could you please connect my mein o2 account to my mobile postpaid contact?

Hello, I have already cancelled my contract. Just ignore it and you can remove my posts
Hello @cemalonur,
but just to ask again: your first contract was about the fact that you are already out of the revocation period. This means that a termination becomes effective at the contractually agreed end of the contract. Is that all correct? And did you get the corresponding SIM card?
Kind regards
Jessica

No, that is not correct. I have already cancelled my contract. However, I received the cancellation confirmation email on February 16. When I spoke to customer service about the status of my SIM card on February 14th, they created a new contract for me. I want to cancel this newly created one.
I sent the cancellation form to widerruf@cc.o2online.de on 17 February.
Hello @cemalonur,
I am very sorry that everything got a bit mixed up!
I just checked your data again - there is a current contact entry from today for your existing phone number/ your existing contract (phone number: 0176xxxxx518) with the information that the contract should have been deactivated yesterday.
The concern has already been forwarded to the relevant department. As soon as this has been processed, your contract should then be deactivated!
Kind regards
Jessica
Hello @cemalonur,
I have just checked again and can confirm that your tariff has been terminated.
Has your issue been resolved?
Kind regards
