Consumer Redressal

I have purchased my Samsung S 4 ( GT I9000) , IMEI no . 357196059464896 on 8th August 2013 and just after 2 months the display went off , there was no physical damage. The phone started heating badly and the display went off. I have given the phone Samsung Authorized service center - Jameson Telecom Services , Bill no.- 4161102138 on 10 Oct , 2013. But have no response yet , the service center keeps telling me to wait and they will call back but there is no response.I am tired of this , i have missed my several important business things cause of no smartphone , I am really frustrated and troubled from last 20 days and mentally harrassed my Samsung\'s poor service. i want an urgent resolution from your side in this matter.
