How to cancel Macsf by mail
Start with your account details
Macsf will look your account up from what the letter says, so check the policy number, the name on the policy and the date you want cover to end first.
Prepare the letter
The request is prepared in French (template fr), under the subject line “Objet : Demande d'annulation – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 92800 Puteaux. Keep the tracking number it gives you.
Keep the proof of delivery
The receipt dates your request. Look at your next statement for any Macsf charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a insurance or protection plan
Insurers cancel by policy and by effective date, so the request has to name the policy number and the date cover should stop, ideally after replacement cover is in place.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
