Micromax Informatics — Handset problem

Address:

400092

Dear sir,
I deeply regret by purchasing micromax q412 handset. i bought it on 6th feb 2016. after few days of purchase there was problem in handset. my voice doesn't go to the person other side. i gave it to gallery and they keep it for 15 to 20 days and again same problem occurred in few days. total five time i submitted the phone but all useless. i have to spare a day from my job to submit handset and still there is no use. people sitting are not useful to us. they have only one answer that they are trying. price of the phone is 7000. i feel frustrated when have to visit customer care every now and than. i would say people who have hard earn money than they should be away from micromax handset. i have no other tool to recover my money. i don't know how to take governments help in such issues.
