How to cancel Sofinco by mail
Get your account details together
Check the account email, the last four digits of the linked bank account or card and the membership tier before anything else. A request that does not match the account on file at Sofinco is the easiest one to set aside.
Write the cancellation request
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Sofinco to close the subscription, stop billing and confirm in writing.
Mail it with tracking
Address the envelope to Sofinco, Massy, 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 Sofinco 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.

Before you cancel Sofinco, check these
- Ask for the direct debit or card authorisation to be ended, not only the membership.

- Check your bank statement after the cancellation date for any further charge.

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.
