Hp — Delay in laptop repairs

Address:

Mumbai City, Maharashtra

I have purchased an HP laptop whose details have been emailed today(10 july 13) to n.[protected]@hp.com,[protected]@hp.com
from US,TX 77433
I have the warranty of the laptop.The hp service centre at aforeserve.com dadar(w), mumbai
-400028, India have identified Dead Battery as problem, but have not replaced it since 3rd july
of 2013.I study outside mumbai,india and will be leaving shortly for my education. Its been 7 days and
still they say they have not got the approval for replacement of battery. The call receiver on
[protected]/07/09 told me they need to get approval from Bangalore, India.The person also
suggested I call US tolI free number.
I hope hp services reply as soon as possible.

What should I do? I have to go outside mumbai for education purpose and my laptop and its battery which I submitted in mumbai has not be replaced.Can someone suggest
