Amazon India — Warranty Not updated as per the buying date for the laptop bought

Address:	Bangalore, Karnataka, 566093

Dear Sir/Madam,

I have bought Dell Laptop from amazon India but the warranty is not as per my buying date, it is showing some old date. I faced some issue with my laptop and i went to service center for repairing but they said that the warranty is 1st Sept 2016 and it is not as per the bill which i got it from amazon. I bought the laptop on 7th Oct 2015 so my 1 year warranty should be till 7th oct 2016 but it is showing as 1st september in the dell database.
I have raised this concern with the Amazon technical support team, for which they have said that it is going to be resolved within 24 to 48 hrs but it has been more than 20 days but still the warranty is not extended. Because of which i am able to give my laptop for service. I would request the concerned department to look into my issue and resolve it.
