Cancelación de pago

[rfalfaro]

When using the payment button, it returns back a message initially stating that it is processing the payment but then proceeds to state that it is being cancelled.

Initial callback after user is notified of supposedly successful transaction:
"Se confirmó el pago, el comercio está realizando el cobro. Por favor espera un momento."

Message displayed a few seconds later:
"El pago está siendo cancelado. Por favor espere un momento."

I can't find any reference to this scenario in the documentation.
