How to cancel K Net by mail
Find your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to K Net is only as good as the details it quotes.
Draft 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 K Net to close the subscription, stop billing and confirm in writing.
Mail the letter with a receipt
Post it by certified mail to K Net in Lyon, France, using the exact address below, and note the tracking number.
Keep proof the letter arrived
The receipt dates your request. Look at your next statement for any K Net charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your K Net cancellation letter goes
K Net takes its post at Boulevard Marius Vivier Merle 96, 69003 Lyon, France, which is where a cancellation letter belongs.
The postcode 69003 belongs to Auvergne-Rhône-Alpes, France, so this is where the envelope is delivered.
The letter is addressed “À qui de droit,” and its details block uses the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel K Net, check these
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
