How to cancel Contnet by mail
Gather your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Contnet names the right account the first time.
Set out the 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.
Mail the letter with a receipt
Address the envelope to Contnet, München, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Hold on to the receipt
Delivery confirmation is your evidence that Contnet was asked. Watch the next statement or two for any further Contnet charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Contnet, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
