[Resolved]  Micromax — Not getting back handset from service centre

I deposited my micromax mobile handset on 17.07.2014 at micromax service centre at Palwal, Haryana for some minor problems. The model was micromax Unite 106, , The Docket No. is N[protected].The service centre promised me to return the handset not more than 10-15 days. Unfortunately there is two month over, & amp; I have not get it back till date. I have visited that service centre many times, but every time they are unable to inform me how long I have to wait. I have complaint to the Costumer Care on 04.09.2014 complaint no. is [protected], they also promise me to rectify my problem within 15 days but 19 days have passed but they also unable to rectify the same. They are again saying to wait for 10-15 day once again. That handset was so much useful to me that I could not live one day without it. So, I am just being mad to get it back as early as possible at any condition. please help me, I will remain ever grateful to you. Thank you :-(
