How to cancel Sftrf by mail
Gather your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Sftrf is the easiest one to set aside.
Draft the request
Postbye writes the letter in French from our French template, because Sftrf's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Sftrf to end the subscription, stop all further charges and confirm in writing.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to 69500 Bron. Keep the tracking number it gives you.
Keep the delivery receipt
Keep the tracking record with your copy of the letter. If Sftrf bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Sftrf cancellation letter goes
For a letter to Sftrf, use Avenue Jean Monnet 260, 69500 Bron, France.
The postcode 69500 belongs to Auvergne-Rhône-Alpes, France, so this is where the envelope is delivered.
Your name, address and email appear in a short block labelled Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, under the greeting “À qui de droit,”.

Before you cancel Sftrf, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
