Yeah, that's surprising to me. I know the guys at GG personally and they are great people. I'm sure it wasn't intentional and that they'll make things right with you.
Is strange that they took your money and then didn't follow up with you though...i have to call them soon about a Noveske upper I ordered 6 weeks ago, though they did say it would take at least this long
