How to cancel Leco by mail
Start with 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 Leco has on file.
Prepare the letter
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.
Post the letter
Address the envelope to Leco, Lille, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
File the delivery record
Delivery confirmation is your evidence that Leco was asked. Watch the next statement or two for any further Leco charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Leco, 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.
