Consumer Redressal

Dear Sir, I had purchased a Samsung GT-i9300 (S3) on 25/10/2013) Serial Number: RZID93SW24X. The phone is under warranty as yet. I have been complaining Samsung about the phone problems since purchase. The Basic issue is that phone\'s performance is very slow. I feel that Samsung has deceived me selling such a low performance phone citing its high end hardware and software configuration. Comparing the hardware configuration of the phone with any other phones including other Samsung phones in Market, this phones works damn slow. I have complaint Samsung for this issue several times but they are reluctant to provide a permanent resolution. Every time I visit service center, they just format the phone and return it back to me. It is a waste of my time and energy to visit it as anyone can do this on its own. It seems that Samsung has purposely made the phone go sluggish with its new software update to that its existing customers switch to its new models available in Market viz S4, S4 mini,
