HTC India — Delay in Service of my HTC Desire 626 mobile phone

Address:

Mumbai City, Maharashtra, 400706

I have given my HTC Desire 626 mobile for service on 28/10/2016, the service center informed me that I will get it back after 8-10 days, I have called them today that is 7/11/2016 but it is still not ready. They told me that I will get it after 8 more days. What is this ? your reputation is like that only ! I have heard from my friends that you people do the service like that only ! please try to overcome your Image !!!
