If you have made a double payment or a payment to the wrong merchant, please contact the merchant. The merchant has to confirm by email (peruutukset@epassi.fi) to Epassi, which payment must be cancelled (payer name, time and amount).
Epassi has no right to interfere with the payments already made without the permission from the merchant. The merchant can also cancel the payment in the Epassi web service if less than a week has elapsed from the payment transaction.
