[Resolved]  Flipkart — laptop warranty registered before the purchase

The laptop i purchased had a warranty of only 306 days while its supposed to be 365 days. It had warranty already already registered before the purchase which is on august while i purchased the laptop on october. Which means laptop was already sold and used in august and sold to me later on.
I received the laptop exactly in a brand new condition but how did it get register on august 2018 in the lenovo website.
This is serious fraud by flipkart
