How to cancel Champion by mail
Find your account details
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 Champion has on file.
Prepare the letter
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Champion to close the subscription, stop billing and confirm in writing.
Post it with proof of delivery
Send it certified to Paris, France, copying the address from the next section letter for letter, and keep the receipt slip.
Keep the delivery receipt
Keep the tracking record with your copy of the letter. If Champion 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.
Where your Champion cancellation letter goes
Champion takes its post at Rue de la Fontaine au Roi 16, 75011 Paris, France, which is where a cancellation letter belongs.
The postcode 75011 belongs to Île-de-France, France, so this is where the envelope is delivered.
The letter is addressed “À qui de droit,” and its details block uses the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Champion, check these
- Check your next statement: no charge should appear after the cancellation date.
- 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.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
