How to cancel Km H by mail
Gather your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Km H names the right account the first time.
Write your request
Because Km H 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 the letter with a receipt
Post it by certified mail to Km H in Paris, France, using the exact address below, and note the tracking number.
Keep the delivery receipt
The receipt dates your request. Look at your next statement for any Km H charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
