HP India — Wrong warranty date

Address:

741101

I have already bought hp Additional 1 year Onsite warranty from hp premium warranty online website at Rs. 199 to extend my warranty 1 years. After 3 days I get a mail from hp that it was given to 2018. But my status is still showing that my warranty is for 1 years. So, I need help. Please solve this warranty problem quickly. I also attached a proof of buying warranty.
