Sony Eric F305 Mobile — Display not working. Poor response from Company

I have bought Sony Ericson F305 model mobile on 9/03/2009 from Telephone Shoppee,Aundh . Within one week of buying there was problem in the display of the handset. Then only I requested to replace the mobile. However, It was told that only repair is possible in the warantee. Mobile was sent through Telephone shoppe to Sony ericson Service centre. After continuous followup, I got my mobile repaired by after almost one month. Now again the same problem is faced .However, When the mobile was sent for repair to Sony ericson centre they refursed to take siting the reqson that there are duplicate parts in the Mobile.

I want to inform all here that Please do not buy any mobile of Sony Ericson expecially F305 and do not by mobile from any outlet of Telephone Shoppe. .
