sprint touch pro MEID/ESN all 0's

[satuday]

I brought a new sprint touch pro from a friend, working fine for 2 months, then the usb stop woring, I called sprint they told me sprint only cover the first month, after that i have to call this other company call pcd, so i called them up, they told me to send the phone in for repair. so I sent the phone in, didnt get it back till like over a month later, and they told me that the phone had physical damage and had illiagal software installed and will not repair it. so i figer i will just have to buy a battery charger for it. then I call sprint to activete the phone again, had the tech on the phone with me for over 3 hours, could not get it to work. so i went to a sprint store to see if they could do it, same thing no luck. so i called my friend who worked at a phone store and did some search online, and found that the ESN and the MEID is all 0's in the EPST screen. so i called PCD again to ask what they do to my phone, they keep saying they didnt do anything to it cause its out of warrenty, strangly that the usb is working fine agian but ESN is erased, i argued with the manager for a hour and he refuse to do anything. does anyone got any suggestion.... please help....
