How to cancel Simplytel by mail
Gather your account details
Have the account number, the phone number or service address being cancelled and the name on the account to hand. The details in the letter need to match what Simplytel has on file.
Put the request in writing
Postbye drafts the request in German, the language of Germany, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks Simplytel to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Send the letter to the Maintal mailing address shown below by certified mail. Keep the tracking number safe.
File the delivery record
File the receipt with the letter. A Simplytel charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
