Micromax Informatics — micromax mobile micromax yu4711(2gb 8gb)(black) mobile model code -serymob018 battery discharging problem

Very sorry to say that though miromax is a good brand my genuine ccomplaint has not been answered since last 1 and 1/2 month.I registered complaint repeatedly vide ser no ser[protected] on 8/10/2017 online. Then another complaint on 18/10/2017 . But to my utter surprise the complaint has not yet been resolved . To narrate the matter once again, i purchased mobile yu4711(2gb 8gb)(black) mobile model code -serymob018 on 10/11/2016. My mobile is in warranty period . It has got problem 5305-y charging/battery backup battery empty. I submitted the phone to your service center on 09/09/2017. However one and half month my phone was handed over ot me on 23/10/2017 and told that the battery has been changed and complaint was closed. Back home when i checked the phone, the same problem persisted. My phone was dicharging within 2-3 hours without any use. This was the same problem for which i had deposited the phone in the service centre of the micromax. I agint visited the service centre of micromax on 28/10/17 and apprised them about the problem that i was facing . They simply formated my mobile this time and told me that the problem has been fixed and your mobile will not discharge in 2-3 hrs now . But agin the same thing happened when i checked the phon at home i.E, my phone was dicharging within 2-3 hours without any use .. For last one and half month i am suffering for no fault of mine. I have lost lot of mental peace and financial loss due to this delay. Under these circumstances may i request you to kindly replace my defective phone and give me a new phone or else i will be left with no other alternative but to file a complaint with the consumer court.
