Motorola Droid Bionic :: It Won't Charge At All

I've had my Bionic since the first week it came out, and, while I generally love the phone, I have had just about every documented problem in existence; I'm fairly sure the employees at my local Verizon store just think I'm trying to scam them into giving me a new phone. Originally, I had the usual data and service connectivity issues-while this was annoying, and did lead to getting me lost in rural Alabama, it seems to have been resolved as I haven't had problems with that in nearly 2 weeks. Then I had the random and frequent power off/black screen of death issues, where even battery pulls wouldn't work. The guy at the Verizon store did a factory reset and everything seemed to be fine for all of 2 weeks. Starting today, my phone will not charge at all. I have used 4 different cables, including the stock USB one that came with the phone, and it will not charge past 5 or 10 percent, and it takes a good hour to get that far. I've also tried charging it in multiple outlets, on my laptop, and using a car charger. Same thing. This is obnoxious, to say the least. To complicate matters, the black screen of death has returned with a vengeance. As of me writing this, I cannot get my phone to respond at all, again, on any charger. I've tried multiple battery pulls, and letting it charge in excess of 30 minutes before attempting to power on, and nothing is working. Every so often I'm lucky enough to get the phone to turn on, just to have it turn back off within 20 minutes or so, all the while remaining at 5% battery. I paid for the insurance from Verizon, but there's no way I'm paying $90 for a replacement phone when I've done nothing to damage the phone-it's been in a case since the first week after I bought it. I'm going back to the Verizon store tomorrow, and unless some miracles occur before then, I'll just refuse to leave without either a new phone, or the RAZR.
