Xiaomi India — Xiaomi Service centre is not returning my phone back.

Address:

Udupi, Karnataka

I gave my phone(Xiaomi MI4) for repair to xiaomi service centre . The problem that i was facing is it won't turn on. I took mi pickup service. it has been 2 weeks now since i have given my to them and i have not recieved any reply from their side and when i call them they either hang up the phone or don't reply. My phone is under warranty. i bought it on 19th of march, 2015.Now i feel like i have given Rs.24000 of charity to xiaomi. My phone was sent to Qarmatek service pvt. ltd., ahmedabad, gujarat - 382445.
