Micromax — Not Deliver Phone

Address:	Gurgaon, Haryana, 122015
Website:	micromaxinfo.com

I submit my phone at MMX Service Center On 4th Sep 2015, and Today is 20th Oct 2015 still not have my phone. When i Call customer care ([protected]), they always say that sir be patent we deliver your phone with in 10 to 15 days but they didn't. What should i do, Is my phone deliver this year or Next year. Seriously the Gadget like Smart phone, Tablet, LCD are good but the Service is Worst Service in India...
