Compra de Xbox Live Gold [Mod Translation - Purchase of xbox live gold]

Hice una compra de un mes de xbox live, y me denego la compra pero si me hizo el cargo de la compra en mi tarjeta y me cobro 276 pesos a pesar de que me aparecio que no lo pude comprar. Que puedo hacer? se me regresa automaticamente mi dinero a la tarjeta?

is my money automatically returned to the card?]
