How to cancel Grunwelt Strom by mail
Find your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Grunwelt Strom is only as good as the details it quotes.
Draft the request
Postbye drafts the request in German, the language of Germany, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks Grunwelt Strom to close the subscription, stop billing and confirm in writing.
Post it with proof of delivery
Address the envelope to Grunwelt Strom, Kaarst, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep proof the letter arrived
File the receipt with the letter. A Grunwelt Strom 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.
Where your Grunwelt Strom cancellation letter goes
Grunwelt Strom takes its post at Girmes-Kreuz-Straße 55, 41564 Kaarst, Germany, which is where a cancellation letter belongs.
Copy the postal code 41564 exactly: it is what routes the letter to Nordrhein-Westfalen, Germany.
Your details go in a block headed by Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse, and the opening line is “Sehr geehrte Damen und Herren,”.

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.
