HTC — Technical problem very frequent

I am using mobile phone htc desire 828 dual sim. Mobile was purchased on 19 march, 2016. My mobile was malfunctioning. Therefore i went to htc collection point ambala. Collection point updated the software. However just by updating the software, problem could not be resolved. As the mobile was under warranty pperiod, therefore i went to htc service cente, chandigarh. The speaker of phone was not working. They resolved the speaker problem but as the removed the strips of speaker to do so, they could not stick strips again properly. I told them to stick properly but they could not. When i was coming back the strips of the speaker got removed from my pocket. The strip of downside speaker fall somewhere and strip o[censored]pward speaker fall into my pocket. I stick the upward side speaker strip with tape to show service center guys and also brought the same matter into the knowledge of htc by email. However i did not get any reply. After again weak or two mobile started to show some new problem, so i again went to service center. Service center guys said the strips will be not be sticked now as one strip has been misplaced but as it was not my fault. Strip was misplaced because of service center carelessness. I made a call to htc customer care. I was told by customer care to send a mail again with photos of the mobile and they will resolve the problem. But no reply has been sent to me yet even after sending a number of mails whenever i call them they said that we will try to resolve your problem. We are apologized. I am fed up with mobile. Showing a lots of problem in just 3 months shows the quality of product. I want replacement of mobile handset or refund the money. Also service center of htc is in chandigarh which is about 50 km from ambala. It is very difficult to travel every time. The strips of speaker must also be sticked as the fault is from htc end in case htc doesnt replace mobile phone
