Nokia 6300
New phone replacement (Display changed but resolution lost)

I Bought a Nokia 6300 phone on dated 16/05 from Harjeet Bros. NOKIA PRIORITY DEALER, Dharampura Bazar, PAtiala. After one and a half months it developed a problem with display and after replacement of Display from Nokia Care, Patiala Centre, after just one day it is again showing resolution defect (resolution is too less with camera). So I want my phone to be replaced or cash back.

Thanks
