Missing Credit

I'm a little sad that I'm not getting my Channel Fireball credit. I worked an extra day on Friday for Grand Prix: Las Vegas and didn't get cash for working that day as I was supposed to. They ran out so asked if I could get a check later. I told them I'd be fine with either check or credit. Credit was easier for them so we agreed to that. In the end, after emailing Sean C. a couple of times with only one response of (paraphrasing) "they'll get to it later" I still haven't recieved my credit. Its completely understandable that they would forget and miss this, but it's still quite annoying for me. All I wanted to do was spend money on their store. Now I can't even do that...
