Samsung Sgh F490 — not servicing

I had bought a Samsung SGHF490 in last sept 2008. Recnetly the mobile was not getting charged. I had given the same for service, they had taken the same and given the acknowlgement. After 6 hours they are calling me and telling it is not repairable and if at all it is to be repaired I have to pay for the same and they dont know how much is the amount..

This is how samsung cheats...Is it the way customers are to be treated...

I had given the same for service in India >> Bangalore >> BTM layout
