Today I bought a couple UGC at a local 7/11 because I'm bored... The guy slid them to activate them. When I came home it said both pins were invalid, anyone help me out here? I went back and he slid them but same results and the paybycash people won't do shit. (called them twice)

never happened to me... weird.

I had the same problem. I tried using the UGC for $20 and it kept saying invalid. I asked runescape, wal-mart (was where I bought it), paybycash, I did everything, no luck. All the best of luck though.

They won't and they have the receipt, they barely speak english too. Might go get them shut down and pull a cartmen on their asses.
