Buzzmeeh — Apple 5S

I have raise a request for Apple 5s on 23sep as it was not working. The executive visit and changed the screen for apple 5s but the phone was not working properly. It was getting lock by its own and dialing emergency no automatically. When I asked the executive that why this is happening you just changed the screen, he replied oh as i just replaced it, it will take some time and this problem will get resolved. Since then it is not resolved yet. It is just 3 days the technician repaired the phone. They are saying that they are providing the warranty of 6months.I am raising the complaints again and again. I am continously chasing them but no body is listening. I have paid the amount whatever they asked for but the problem is not resolved yet. They are not at all a good service provider, I must say. Either provide me a refund or solve the issue. I have paid 1500 in cash and 1000 rs as a voucher.
