Consumer Redressal

I had purchased my Samsung Galaxy S III on 08 Jan 2013. However the set has always been of substandard and was extremely slow as well as used to take 14 to 15 hrs to charge . Thus I took the phone to Samsung service centre in May 2013 for rectification of the said complaints. My phone was kept at the service centre for 08 days and the phone\'s Mother board, Adapter and Data cable were replaced. However the phone\'s performance did not show much of an improvement. Moreover from last one month the phone phone\'s bty ditches completely within a period of just 4-5 hrs even in standby mode and is thus reqd to charged atleast 3 times in a day. More ever, the performance which includes the speed is very poor. I showed the same to the service center on which they say that there is some problem in the mother board and need to replaced. I would like the company to replace the set and provide me a new S4 one as I am facing hell lot of problem since the day i bought.
