How to cancel Dus Net by mail

  1. Note your account details

    Put the account number, the phone number or service address being cancelled and the name on the account in front of you before you write: the request to Dus Net is only as good as the details it quotes.

  2. Write your request

    The request is prepared in German (template de), under the subject line “Betreff: Kündigungsanfrage – [your name]”: end the subscription, stop all further charges and confirm in writing to you.

  3. Post the letter

    Send the letter to the Düsseldorf mailing address shown below by certified mail. Keep the tracking number safe.

  4. File the delivery record

    File the receipt with the letter. A Dus Net charge dated after delivery is the one to dispute, and these two documents are what you quote.
