How to cancel Swisscontact by mail
Start with your account details
Put your donor or supporter number, the name on the donation and the amount and date of the latest payment in front of you before you write: the request to Swisscontact is only as good as the details it quotes.
Put the request in writing
Because Swisscontact is dealt with in German, the letter is written in German (template de). Subject: “Betreff: Kündigungsanfrage – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Post the letter
Send it certified to Zürich, Switzerland, copying the address from the next section letter for letter, and keep the receipt slip.
Save the tracking record
File the receipt with the letter. A Swisscontact 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.
Where your Swisscontact cancellation letter goes
Swisscontact can be reached by post at Hardturmstrasse 123, kundenservice, 8005 Zürich, Switzerland.
Copy the postal code 8005 exactly: it is what routes the letter to Zürich, Switzerland.
Your name, address and email appear in a short block labelled Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse, under the greeting “Sehr geehrte Damen und Herren,”.

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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
