HTC — not repairing mobile in warranty

Address:

Gautam Buddh Nagar, Uttar Pradesh

I have purchased a new HTC mobile on 2 March 2015 in 19990/- thousands (HTC Desire 816) and on 6 June 2015 it causes some hardware issue (outgoing voice problem/speaker Lower is not working). So I have submitted the mobile to registered service centre at Noida on 12 June 2015 because it was in warranty, and after that 42 days have been passed and the service centre is neither repairing my mobile nor returning it to me. I am calling to customer care number from last 20 days twice or thrice in a day and they are not giving any satisfactory answer to me and even they are miss-behaving also. They put my call on hold and say let then check the status and after 10-15 minutes they came back and say they are raising some complain to higher department. And on 20 July 2015 they returned my mobile to service centre without repairing it, and when I call him for status they are saying please resubmit it, even I don’t received my mobile. Some peoples from customer care team are also talking in arrogant language, and when I am asking to refund my money or replace my device they are advising me to please put the call on hold and read the warranty statement first. Still on Today 23 July 2015 I have called him to know any update for my mobile they are saying to wait for 10 working days more, and denying to refund my money and replacement of my device. I am very frustrated from there service and there way of talking to customers.
