How to cancel Callant by mail
Get your account details together
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Callant can only act on a request it can match to an account.
Prepare the letter
Postbye writes the letter in French from our French template, because Callant's address is in Belgium. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Callant to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Send it certified to Antwerpen, Belgium, copying the address from the next section letter for letter, and keep the receipt slip.
File the delivery record
The receipt dates your request. Look at your next statement for any Callant charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Callant, 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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
