How to cancel Telenet by mail

  1. Gather your account details

    Telenet will look your account up from what the letter says, so check the account number, the phone number or service address being cancelled and the name on the account first.

  2. Write your request

    The request is prepared in French (template fr), under the subject line “Objet : Demande d'annulation – [your name]”: end the subscription, stop all further charges and confirm in writing to you.

  3. Send it by certified mail

    Take the letter to the post office and ask for certified delivery to 2800 Mechelen. Keep the tracking number it gives you.

  4. Hold on to the receipt

    Once the letter is delivered, the date on the receipt is the date Telenet was told. Compare it with your statements over the next billing cycle.

With Postbye, steps 2 to 4 take about two minutes of your time.

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.
