My jasjar wont turn on PLEASE PLEASE PLEASE HELP

HI i really need help any info is greatly appreciated, today i dropped my phone and it hit it on the side where the memory card goes in, the outside is a little scuffed up, after that happened i believe the keyboard was hot or maybe it was because the phone was in my pocket earlier, when the phone fell the battery cover came of.. now the phone wont turn on.. when i came home i plugged it into the charger but no luck. when i take out the battery and plug it in.. a red light on the right side of the unit comes on but when i put the battery in and charge it nothing happens. i tried doing a hard reset, nothing happened. same with soft reset. i have taken out the battery and im gonna leave it alone for a little bit.. now i bought this phone of ebay a week ago of someone who used it themselve. i tried to register it on clubimate.com but it wont let me because the IMEI is already used. i really dont know what to do.. does anyone know where i can send it to get it fixed or if i can fix it myself? any info is much appreciated... it took me 2 months to save enough money to buy the phone and it died after only one week, thank you all in advance BeN
