How to cancel Com Professional 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 Com Professional is only as good as the details it quotes.
Write your 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.
Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to 80015 Munich. Keep the tracking number it gives you.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Com Professional was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Com Professional cancellation letter goes
The mailing address we hold for Com Professional is Postfach 201552, 80015 Munich, Germany.
“Postfach 201552” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
The letter greets the reader with “Sehr geehrte Damen und Herren,”; your own details sit under the labels Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse.

Before you cancel Com Professional, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- 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.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
