If you or a customer has made an incorrect payment or used the wrong OCR number when making a payment to Billogram, you need to contact support@billogram.com and include a receipt of the payment in the e-mail. 

The receipt is available from your internet bank and should clearly show recipient, sender, date, amount transferred, and reference. After that we can return the money or transfer it to the invoice it was originally intended for if you provide the correct OCR number in your e-mail.
