How to cancel One Tel by mail
Note your account details
Put the account number, the phone number or service address being cancelled and the name on the account in front of you before you write: the request to One Tel is only as good as the details it quotes.
Put the request in writing
Because One Tel 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.
Send the letter by certified mail
Address the envelope to One Tel, Paris, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
File the delivery record
Delivery confirmation is your evidence that One Tel was asked. Watch the next statement or two for any further One Tel charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your One Tel cancellation letter goes
One Tel lists Rue des Cottages 4, 75018 Paris, France as its mailing address.
Copy the postal code 75018 exactly: it is what routes the letter to Île-de-France, France.
Your details go in a block headed by Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, and the opening line is “À qui de droit,”.

Cancelling a phone or internet plan
Phone and internet providers tie cancellation to contracts, equipment balances and notice periods, so the request should name the exact line or service and ask for a final bill in writing.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
