How to cancel Biron by mail
Start with your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Biron names the right account the first time.
Write the cancellation request
State plainly that you want the Biron account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Cancellation Request – [your name]”).
Mail the letter with a receipt
Address the envelope to Biron, Brossard, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the proof of delivery
File the receipt with the letter. A Biron charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Biron lists Boulevard Matte 4105, Porte F, J4Y 2Z2 Brossard, Canada as its mailing address.
The postcode J4Y 2Z2 belongs to Quebec, Canada, so this is where the envelope is delivered.

Before you cancel Biron, 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.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
