Put the request in writing

Post the letter
Send it certified to Altomünster, Germany, copying the address from the next section letter for letter, and keep the receipt slip.
File the delivery record
Delivery confirmation is your evidence that Altonetz was asked. Watch the next statement or two for any further Altonetz charge.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
