How to cancel Cliniclowns by mail
Collect the details you need
Have your donor or supporter number, the name on the donation and the amount and date of the latest payment to hand. The details in the letter need to match what Cliniclowns has on file.
Set out the request
Postbye writes the letter in Dutch from our Dutch template, because Cliniclowns's address is in Netherlands. It opens with the subject line “Onderwerp: annuleringsverzoek – [your name]” and asks Cliniclowns to end the subscription, stop all further charges and confirm in writing.
Post it with proof of delivery
Send it certified to Amersfoort, Netherlands, copying the address from the next section letter for letter, and keep the receipt slip.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Cliniclowns 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 Cliniclowns cancellation letter goes
For a letter to Cliniclowns, use Postbus 1565, 3800 BN Amersfoort, Netherlands.
“Postbus 1565” 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.
The database also lists Prins Boudewijnlaan 141, afdeling Klantendienst, 2610 Antwerpen, Belgium for Cliniclowns. Use the first address above unless your agreement names this one.
The letter greets the reader with “Geachte heer/mevrouw,”; your own details sit under the labels Accounthouder, Factuuradres in dossier and E-mailadres in dossier.

Cancelling a regular donation
Regular donations run until the donor ends them, so a written request should give the donor reference and ask the charity to stop the payment and confirm the end date.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
