How to cancel Antargaz by mail
Start with your account details
Antargaz 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.
Set out the request
Postbye writes the letter in French from our French template, because Antargaz's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Antargaz to end the subscription, stop all further charges and confirm in writing.
Send the letter by certified mail
Use certified mail for the 92400 Courbevoie address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the proof of delivery
The receipt dates your request. Look at your next statement for any Antargaz charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Antargaz cancellation letter goes
Written requests to Antargaz go to Place de Saverne 3, 92400 Courbevoie, France.
The postcode 92400 belongs to Île-de-France, France, so this is where the envelope is delivered.

Before you cancel Antargaz, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- 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.
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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
