How to cancel G Portal by mail
Start with your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details G Portal holds, so the request can be matched to your account.
Draft the request
Postbye writes the letter in German from our German template, because G Portal's address is in Germany. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks G Portal to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Address the envelope to G Portal, München, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
File the delivery record
File the receipt with the letter. A G Portal 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.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
