How to cancel Calypsor Vzw by mail
Find your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Calypsor Vzw is the easiest one to set aside.
Write your request
Postbye drafts the request in French, the language of Belgium, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Calypsor Vzw to close the subscription, stop billing and confirm in writing.
Mail the letter with a receipt
Send it certified to Bruxelles, Belgium, copying the address from the next section letter for letter, and keep the receipt slip.
Hold on to the receipt
File the receipt with the letter. A Calypsor Vzw 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.

Before you cancel Calypsor Vzw, check these
- 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.
- Use the same name and email as on the account. A mismatch can delay the request.
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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
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.
