How to cancel Harmonie Mutuelle by mail
Gather your account details
Have the policy number, the name on the policy and the date you want cover to end to hand. The details in the letter need to match what Harmonie Mutuelle has on file.
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 Harmonie Mutuelle to close the subscription, stop billing and confirm in writing.
Mail it with tracking
Mail the letter by certified mail to the Paris address in the next section, and keep the tracking number.
Keep the delivery receipt
Once the letter is delivered, the date on the receipt is the date Harmonie Mutuelle 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 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.
