Contact form help DSL contract cancel

[Sunilrjpt3]

Hi ,

I am filling contact form to  cancel my dsl contract. But I am not sure what to add in  "Ihr persönliches Kunden- oder Teilnehmerpasswort"  or Customer /subscriber password. I checked my contract there is no such password mentioned. Please help. @Andre 

Thanks

You set this customer password while ordering the contract...

The other way would be to send a written cancellation notice using postal mail if you cannot remember that customer password.

And please keep in mind to send the cancellation in German language.
