How to cancel Adcf by mail
Collect the details you need
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Adcf is the easiest one to set aside.
Draft 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
Use certified mail for the 10117 Berlin address in the next section, so the post office records the delivery. Write down the tracking number.
Hold on to the receipt
Keep the tracking record with your copy of the letter. If Adcf bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Adcf cancellation letter goes
Adcf takes its post at Anton-Wilhelm-Amo-Straße 69, 10117 Berlin, Germany, which is where a cancellation letter belongs.
The envelope is going to Berlin, Germany, so the postcode 10117 must be on the front.
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,”.

Before you cancel Adcf, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- 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.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
