How to cancel Assor by mail
Note your account details
Assor 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.
Write your 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.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 92000 Nanterre. Keep the tracking number it gives you.
Hold on to the receipt
Keep the tracking record with your copy of the letter. If Assor 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.

Before you cancel Assor, check these
- 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.
- Use the same name and email as on the account. A mismatch can delay the request.
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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
