How to cancel Kwf Kankerbestrijding by mail
Get your account details together
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Kwf Kankerbestrijding can only act on a request it can match to an account.
Set out the request
Kwf Kankerbestrijding 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.
Post it with proof of delivery
Post it by certified mail to Kwf Kankerbestrijding in Amsterdam, Netherlands, using the exact address below, and note the tracking number.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Kwf Kankerbestrijding 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.
Where your Kwf Kankerbestrijding cancellation letter goes
Kwf Kankerbestrijding takes its post at Postbus 75508, 1070 AM Amsterdam, Netherlands, which is where a cancellation letter belongs.
“Postbus 75508” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
Inside, the salutation reads “Geachte heer/mevrouw,”, followed by your details under Accounthouder, Factuuradres in dossier and E-mailadres in dossier.

Before you cancel Kwf Kankerbestrijding, 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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
