How to cancel Security Cwi by mail
Find your account details
You will need the account or subscription number, the email the plan was bought with and the address or devices it covers. Use exactly the details Security Cwi holds, so the request can be matched to your account.
Write your request
Because Security Cwi is dealt with in French, the letter is written in French (template fr). Subject: “Objet : Demande d'annulation – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Mail it with tracking
Mail the letter by certified mail to the Aix-en-Provence address in the next section, and keep the tracking number.
File the delivery record
Once the letter is delivered, the date on the receipt is the date Security Cwi 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.

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.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
