How to cancel Carte Castorama by mail
Note your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Carte Castorama is the easiest one to set aside.
Put the request in writing
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Carte Castorama to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Mail the letter by certified mail to the Avon address in the next section, and keep the tracking number.
File the delivery record
It shows the date Carte Castorama received your letter. Check your next statement: no Carte Castorama charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Carte Castorama cancellation letter goes
Carte Castorama takes its post at BP 50075, 77210 Avon, France, which is where a cancellation letter belongs.
The envelope is going to Avon in Île-de-France, France, so the postcode 77210 must be on the front.
Your name, address and email appear in a short block labelled Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, under the greeting “À qui de droit,”.

Before you cancel Carte Castorama, 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
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.
