C510 Help!

Hey fellow forum members,

I recently bought the C510 and is locked under Rogers network only. I went to a market to get it unlocked and used the number code from "<, *, *, <". Thus it saying "Network Unlocked" I put in my sim and only got "Inactive SIM". Found out that the phone is blacklisted/stolen. I get signal on the phone but no incomming or outgoing calls/txt
Should I go get my refund at the store I purchased it from and threaten him I'd call the police for having a stolen phone? or does anyone know of anyway of making it work/unlock? I also have tried Aerix multiple times, I get no progress.
I don't think SeTools 2 Lite has my phone model nor C905 to do anything.

Thanks,
Aspect
:(

I also, can't seem to access my "<, *, *, <" network unlocking code screen.

Man, go and give it back, get your money and buy a new one!
