Just been informed that my purchase has been refunded

have to wait and see now how long it takes i guess. I have just tried to purchase it again on a different card but everytime i try and click confirm to get to the payment screen it keeps giving me an error the page cannot be displayed everytime! so annoying. I tried buying a different game and it seemed to work fine, are you only allowed 1 kep per game from GMG? If you are im guessing it could be blocking me from trying to get another one even tho i dont actually have one.
Did you have any issues buying another one?
thanks again
