How to cancel KPN Telefoon by mail
Collect the details you need
Check the account number, the phone number or service address being cancelled and the name on the account before anything else. A request that does not match the account on file at KPN Telefoon is the easiest one to set aside.
Write the cancellation request
KPN Telefoon is based in Netherlands, so the letter goes out in Dutch, built from our Dutch template. Subject line: “Onderwerp: annuleringsverzoek – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 3072 AP Rotterdam. Keep the tracking number it gives you.
Keep the proof of delivery
Delivery confirmation is your evidence that KPN Telefoon was asked. Watch the next statement or two for any further KPN Telefoon charge.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
