How to cancel Comdirect by mail
Note your account details
Start with the account email, the last four digits of the linked bank account or card and the membership tier, so the request to Comdirect names the right account the first time.
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.
Mail the letter with a receipt
Mail the letter by certified mail to the Quickborn address in the next section, and keep the tracking number.
Hold on to the receipt
Keep the tracking record with your copy of the letter. If Comdirect 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.

Before you cancel Comdirect, check these
- Check your bank statement after the cancellation date for any further charge.
- Settle any outstanding balance first. Closing a membership does not clear what you owe.
- Ask for the direct debit or card authorisation to be ended, not only the membership.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a finance or credit subscription
Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
