Micromax — Service centre not returning my phone - micromax

Address:

Chandigarh, Chandigarh

Sir,
I purchased a micromax canvas juice 2 on 25.05.2015. From starting onwards i was experiencing overheating problem and display problem in my handset. On 11th june this year, i submitted my device in service centre. First they said that it will be okay by 13th most probably. When i called them they said it will take time. Then 15th i called again they said its in co. When i contacted the co. They asked for 15 days, i said ok. After a week i contacted them to know my device's status. They again said it would take 15 days or even earlier. Then on 24th when actually the phone has gone through 15 days they said it is under process it would 15 days . Now i am fed up of all this.
Firstly, how come a new gadget is giving such problems. And now its been in the service centre for a greater time than it has been with me. Whenever i call they say the same dialogue like they have memorised it :- " is under process it would take 15 days". I want to ask why are the 15 days not finishing. How much days will you take to repair my device under the context of 15 days. I have even put various mails but they are also stuck at it is under process. Now i am totally unsatisfied with the amount of time you guys are taking.
At last a simple request either repair my device till 5th july or replace it with a new one. When i have not even used it for a month and you can't repair it within time so please replace it.
