Dell India — Warranty period mismatch

Address:

800001

I order a new alienware on 4th of july 2016, and got it delivered on 15th of july 2016.
I tried to register on dell website for warranty and got a result saying its already registered. My service tag number is 72b2n72, and its showing the warranty from march 2016 to march 2017, that means i only get 7 months warranty? I purchased with a full one year premium warranty. Please resolve the issue.
