Motorola Mobility — Expected delivery date are vague

Address:	New Delhi, Delhi, 110030
Website:	www.motorola.in

My cellphone was dead just after 2 months of its purchase and i got a service note from Motorola mentioning that your cellphone will be delivered to you by 6/jan but even after 10 days i am not having my phone back. Don't know what to do and where to raise my concern. Being a GATE aspirant i needed the cellphone for january month but now it seems like i have to look for an alternative. So this is what I am looking for after paying almost 13K bucks. Please look into this matter as soon as possible so that I can either have my cellphone back or i can get my money refunded through Flipkart.
