It could be that:
Your customer used the wrong payment reference.
Your customer transferred the wrong amount.
Your customer selected World transfer instead of SEPA bank transfer.
If we can’t link the payment reference or amount to the correct webshop, we’ll refund your customer within 2 business days.
Once they receive their refund, you can ask your customer to transfer the correct amount again using the correct payment reference. If the payment details are correct, we’ll receive the amount within 2-3 days and update the transaction status in your Mollie Dashboard.
