Nokia India — Faulty handset, want replacement.

Address:

New Delhi, Delhi

I am using Nokia Lumia 920. Recetly, Vibration was not working so I visited Nokia Service Center. They asked me to submit my phone for 10-12 days. Today, I got it back and now Mic has stopped working. Again they submitted it for 10 days! My phone is under warranty and I need replacement. Nokia Centere where I submitted my phone is: "Service & Communication[213_433527]" of "A-180, Sukhdev Nagar Market, Kotla Mubarakpur, Opp. Defence Colony, New Delhi-110003". Phone Model: Nokia Lumia 920. IMEI No.: [protected]
