How to cancel Trombosestichting by mail
Start with your account details
Before writing, collect your donor or supporter number, the name on the donation and the amount and date of the latest payment. Trombosestichting can only act on a request it can match to an account.
Write the cancellation request
Postbye drafts the request in Dutch, the language of Netherlands, with “Onderwerp: annuleringsverzoek – [your name]” as the subject line. It asks Trombosestichting to close the subscription, stop billing and confirm in writing.
Send it by certified mail
Post it by certified mail to Trombosestichting in Voorschoten, Netherlands, using the exact address below, and note the tracking number.
Keep proof the letter arrived
File the receipt with the letter. A Trombosestichting charge dated after delivery is the one to dispute, and these two documents are what you quote.
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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
