How to cancel Garantie M by mail
Gather your account details
Garantie M will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Put the request in writing
Garantie M is based in France, so the letter goes out in French, built from our French template. Subject line: “Objet : Demande d'annulation – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to 69100 Villeurbanne. Keep the tracking number it gives you.
Keep proof the letter arrived
Keep the tracking record with your copy of the letter. If Garantie M 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.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
