InFocus — Not received back my smartphone from service centre

On 14 October 2015, I had bought an infocus smartphone from snapdeal. On 8 August 2016, it developed a malfunction and only a white light was flashing on it. The next day I went to infocus service center to get it repaired and they said that it will take eight to ten days to repair it. Now it is almost a month and I had not received any information on its progress or whereabouts. Whenever I tried to contact the service center or infocus customer care, they just simply ignored me by saying that it will take time. I had also written a mail to them but then also I was not satisfied by their reply.
