How to cancel Protectline by mail
Start with your account details
Before writing, collect the account or subscription number, the email the plan was bought with and the address or devices it covers. Protectline can only act on a request it can match to an account.
Set out the request
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Protectline to close the subscription, stop billing and confirm in writing.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to 93160 Noisy-le-Grand. Keep the tracking number it gives you.
Keep proof the letter arrived
File the receipt with the letter. A Protectline 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.
Where your Protectline cancellation letter goes
Protectline lists Place Jean-Baptiste Clément 1, 93160 Noisy-le-Grand, France as its mailing address.
The envelope is going to Noisy-le-Grand in Île-de-France, France, so the postcode 93160 must be on the front.
Inside, the salutation reads “À qui de droit,”, followed by your details under Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Cancelling a security or identity-protection subscription
Security subscriptions often auto-renew and monitored plans can sit on a fixed contract term, so it matters when the request reaches the provider and whether it covers every device or location.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
