[Resolved]  Sony Ericsson — Frequently giving error,hanging,auto switch off,chrger not working

I have bought a Sony Ericsson K220i mobile from BIG C, Ammerpet, Hyderabad on december 2008. The mobile set was recommended by the shop owner and i bought it with a hope that the mobile will perform becuase of the reputation the manufacturer it carries. It is the biggest blunder i have done in my life. The mobile was getting switched off automatically, frequently giving error(Please try leater), charger not working..

Since 2 months i am running customer care to rectfy the error..But till yet the problem is not rectfied..

I don't know how many months i will have to run to job center of sony erricssion..

When contacted to customer care, they are getting irritated..So i don't understand what to do.
