Sony ericsson w580i
No repair done

I purchased new sony ericsson w580i handset worth rs 12000

but after two months it fell in water so stopped working. i went to sony ericsson service centre several times but they declared the set as dead set . i told them that i am ready to pay for the damage but they said parts are unavailable.i am not in a position to buy a new hand set.i dont know if i cant get parts from the company itself so where should i go. i lost rs12000 from my hard earned money and dont know what to do

plz guide me
