Warranty date incorrect

Hi,

I purchased a new laptop - E5-573-36RP on 16th Apr 2016. When checking the warranty online here(https://www.shopacer.co.in/) , I see the expiry date is 3rd April 2017 which is incorrect. I also want to purchase extended warranty. How do I go about correcting the expiry date and purchase of extended warranty?

Thanks!
