You're probably scheduled for a 10/5 delivery, right? Don't worry. You won't be charged until your phone is shipped. And since the 9/28 people haven't even gotten their phones shipped you still have a while to wait. I'd expect a cc charge next week about Wednesday.
Hm, I got mine minutes after preordering.
I'd definitely give a call to verizon about it. It may be that the order didn't fully go through. I wouldn't recommend ordering again though until you're absolutely sure about the first order being gone to avoid getting two phones on accident.
