HTC — repair of htc desire 820 under warranty

Just 3 months ago i purchased htc desire 820. But now in this short time i faced problem of speaker/ringer. I showed the phone at Your Patiala service centre. I was asked to submit my cell phone to them for a week for repair as they were not able to repair at their service centre. I deposited my phone with them on 09/02/2015 under Ticket no 15INA[protected]. But when i tracked my phone repair status it is still under repair. I am not clear when will i get my cell phone back after repair. It is very difficult to be without a smart phone in toady's life.
