Micromax — Service delay in mobile repairing

Address:

Kanpur, Uttar Pradesh

I have submitted my Micromax Canvas 2.2 A114 on 10th July, 2015 at Micromax Care Govind Nagar Kanpur UP for repairing of power switch problem. Firstly they told me to collect phone after 2 Days but when i inquired about my phone after 2 Days, they said that it is not repaired and informed to collect the phone after one week. From that day they are providing one week timing regularly. I am not to get my phone yet and no correct information they are providing. When I asked them for how much time it will take to repair, they are communicating rudely and irresponsibly . Its been more than one month and still I am not sure how much time it will take. Note: They promise to give service in one week. What should I do now. Please help me.
