Everyone makes mistakes. Once your payment status changes to "Transfer initiated", we can't cancel it. The money's already left your account and is moving through the payment network.
Some banks may reject the transfer back automatically if the name doesn't match with the account number, but this varies depending on the currency and bank that you sent to.
If you sent funds to a wrong account or you would like to receive the funds back, the easiest and fastest solution is to directly contact the beneficiary of your transfer, explain the mistake and ask them to return the money to your account. You may need to provide them the bank account details for receiving the funds back on your Krak account.
If for some reason this option is not available to you, please contact support.
