Sony Ericsson W395 — Hanging

I am praveen from chennai i got Sony ericssion W395 mobile last month the phone is having severe problem like hanging when playing mp3 songs since its walkman series phone it has the hanging problem while playing the song. I spent nearly my month salary to buy the phone after seeing that problem i got very much depressed with that ..it seems to be no value for the money which i spent its seems to be a mental torture for me ..I would ask for the my money back..which i spent..
