Ask them to open up another ticket and have them investigate into it. It doesn't seem fair that u ordered it first day but never got that kit but others have. Even a credit or something to offer u would be helpful.
After having a G4 since launch day, I can tell you that it is indeed amazing. The camera. Wow. Some of the shots I have gotten with it so far are incredible. The only issue I have found is the intermittent touchscreen misfire. That will be fixed with a software update I hope.
This is but one shot I have captured with the G4 camera.
