Orders are processed automatically and instantaneously after receiving confirmation from PayByCash that the order is complete. If you believe there to be a problem in the processing of your PayByCash order you can e-mail
help@paybycash.com however PayByCash processing can take longer than normal if they are doing extra authentication on the validity on an order.
Since you in particular have had reversed payments in the past it is not surprising that they would be doing some extra verification on your order.
