How to cancel Prefon by mail
Get your account details together
Have the account email, the last four digits of the linked bank account or card and the membership tier to hand. The details in the letter need to match what Prefon has on file.
Draft the request
Because Prefon 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.
Post the letter
Send it certified to Toulon, France, copying the address from the next section letter for letter, and keep the receipt slip.
Keep proof the letter arrived
It shows the date Prefon received your letter. Check your next statement: no Prefon charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Prefon cancellation letter goes
Prefon can be reached by post at Rue Nicolas Appert, 83100 Toulon, France.
Copy the postal code 83100 exactly: it is what routes the letter to Provence-Alpes-Côte d'Azur, France.
The letter greets the reader with “À qui de droit,”; your own details sit under the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Cancelling a finance or credit subscription
Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
