How to cancel Hartstichting by mail
Get your account details together
You will need your donor or supporter number, the name on the donation and the amount and date of the latest payment. Use exactly the details Hartstichting holds, so the request can be matched to your account.
Write the cancellation request
Hartstichting 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
Send it certified to Den Haag, Netherlands, copying the address from the next section letter for letter, and keep the receipt slip.
Save the tracking record
Delivery confirmation is your evidence that Hartstichting was asked. Watch the next statement or two for any further Hartstichting charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
