Query: Terrible Phone!!!

I got this phone in October of 2008 and in the begining it was all right. I only had to charge it up and it would last for at least 4 days. Then only weeks later it started to get weaker and weaker and eventually if I wasn't talking on it, it was on the charger. Then as if it couldn't get any better the the dang thing just shuts off when it wants to. It says that it has a low battery and shuts off as if the battery has give out, but only 5 mins. before, it had a full charge. It also continues to do this even after a software upgrade and new battery. And verizon isn't much help either. The guys who sold me the phone and swore how good it was is pretty much telling me now that its not their problem and I don't have another upgrade until October of this year. VERIZON AND THE KRAZR SUCK!!! I swear I'm going to AllTell!!
