HTC — Bad customer service

Address:

Chennai, Tamil Nadu

I given my mobile Desire 816G for service in TVS HTC service center Chennai, 2 time they replaced motherboard and they said like they replaced sub board also but still the problem is no resolved every time they telling me some reasons, i really very frustrated about their behavior and no proper response. First i had sim slot problem they replaced it after replacing volume down button didn't worked and auto rotation problem. Second time again i faced the sim slot problem they said it was problem in Motherboard and replaced it after replacing the motherboard mic didn't worked, within a week again i walked to service center, Third time they said they replaced mic board when i checked the mobile in service center it self it didn't worked. Now they telling motherboard need to replaced. I think they killed my mobile they changed all the parts in mobile expect the display.
