I'm starting to get extremely ticked off at this system for buying points. I probably spent two hours yesterday typing in credit card information to get a 5 dollar pack and all it kept telling me was there was an error and to try again later. Today I got fed up enough with it to go out and actually buy a 10 dollar prepaid card and now its telling me that the card is not valid. I've checked and double check these numbers and it still does not work, I even ran back to the store to make sure they scanned it. Why the heck can't any of this work all I want is the Gragas skin on sale. Riot please help me! At least get my prepaid card to register because I don't feel like wasting my money.
