How to cancel Qasa by mail
Collect the details you need
Qasa will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Put the request in writing
Postbye writes the letter in Swedish from our Swedish template, because Qasa's address is in Sweden. It opens with the subject line “Ämne: Begäran om uppsägning – [your name]” and asks Qasa to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Post it by certified mail to Qasa in Stockholm, Sweden, using the exact address below, and note the tracking number.
Hold on to the receipt
Delivery confirmation is your evidence that Qasa was asked. Watch the next statement or two for any further Qasa charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Qasa, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
