How to cancel Carrefour by mail
Get your account details together
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Carrefour has on file.
Write the cancellation request
The request is prepared in French (template fr), under the subject line “Objet : Demande d'annulation – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Send it by certified mail
Mail the letter by certified mail to the Loire-Authion address in the next section, and keep the tracking number.
Keep the proof of delivery
The receipt dates your request. Look at your next statement for any Carrefour charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Carrefour, 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.
