How to cancel 01Net by mail
Note 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 01Net names the right account the first time.
Write the cancellation request
Postbye writes the letter in French from our French template, because 01Net's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks 01Net to end the subscription, stop all further charges and confirm in writing.
Post the letter
Use certified mail for the 60500 Chantilly address in the next section, so the post office records the delivery. Write down the tracking number.
Keep proof the letter arrived
It shows the date 01Net received your letter. Check your next statement: no 01Net charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your 01Net cancellation letter goes
01Net can be reached by post at Avenue du Général Leclerc 45, 60500 Chantilly, France.
The envelope is going to Chantilly in Hauts-de-France, France, so the postcode 60500 must be on the front.
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 01Net, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- 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.
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 mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
