The payment platform should have communication and refund supported via the API or their website? So for each buyer, there will be a 'Payment support' button that will be displayed on the Bingo Maker page. When someone uses that, the website owners will see a unique number, and a message. The unique number can be used to check/reverse payments made through the solution, and to respond to the message.
