How to cancel Science Et Avenir by mail
Note your account details
Before writing, collect the email on the account, the delivery address for print copies and the subscription or reference number from your latest invoice. Science Et Avenir can only act on a request it can match to an account.
Prepare the letter
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Science Et Avenir to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to 60500 Chantilly. Keep the tracking number it gives you.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Science Et Avenir was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
