HTC — Poor phone and service

Address:

Ernakulam, Kerala

I bought an htc desire 616 two months before. but within this period my phone got a compaint in main camera and audio jack.So i gave it at htc service center at Cochin, Kerala for its repair. They said that its board must be changed and it should arrive from chennai. till now i didnt get my phone back. whenever i call them, they tell me that parts are still pending and not arrived yet.please make a solution for me...
