Hello..
My name is Ratnesh Verma, I bought a Micromax nitro 2 ( E-311) in August 2015, few months it worked properly but after that, its inbuilt Weather application which is a part of Operating system, stopped working at all and touch and camera started malfunctioning, my handset was in warranty so I contacted to the authorized service centre for the problem which I was facing, service centre told me that you have to leave this handset for repairing.
I submitted that mobile handset in the service centre (Job sheet no. – N[protected]) for a repair on 6 June 2016, after 1 month they call me that my handset has been repaired and I can take it back, when I went to take back that set, I asked them for a check, when they checked that set in front of me it was not working, the problems for which I gave it to the service centre were not resolved.
So I refused to take that handset back, after that they made a new jobsheet on 4 July 2016 for repair again (Job sheet no. - N[protected]) from that date my handset is in service centre for repair. After that, service centre send me a Message with another Job sheet (Job sheet No. – N[protected]) on 5 Aug 2016, why another job sheet without my concern? I don’t know.
Several times I contacted on customer care portal (micare.micromaxinfo.com) and write them about my problem, but they didn’t do anything satisfactory.

My handset is in Under repair since 6 June 2016 (Till now it has been passed 5 months), I just want to know that...
1- How many months or year Micromax co. will take to resolve this problem?
2- When will I get my handset back in proper working condition?

Meanwhile in this case, I received several messages from Micromax service centre that my set is repaired and I can take it back, but whenever I went to there, they didn’t gave it to me and said that messages were not send by them ( I have them in my mobile for future references).
