Hello az.ihsan,



no, there is no specific form which you need to use.



You can just write a cancellation by yourself with all the needed information: your personal data, the account number of the contract and the phone number, and the concern to cancel it of course.



The only important thing is that the notice period is 3 months before the runtime end!



Kind regards,



Jessica
