How to cancel Big Bang by mail
Gather 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 Big Bang 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 Big Bang to close the subscription, stop billing and confirm in writing.
Mail it with tracking
Send it certified to Lille, France, copying the address from the next section letter for letter, and keep the receipt slip.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Big Bang was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Big Bang, check these
- 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.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
