[Resolved]  Flipkart — flipkart account hacked and hacker bought goods worth rs 15364/-

Address:	560066
Website:	flipkart.com

My registered email id and mobile number has been changed, the hacker bought using buy now pay later option and the bill was sent to me of rs.15364/-
I have immediately given complaint to flipkart stating all the information many times but no action taken from flipkart side instead they said it will be resolved by 48 hrs and by now it is already 3 months and now flipkart is asking me pay the money. The thing which is very scary for me is flipkart still not taken any action against the hacker even after providing the hackers mobile number and if this continues hacker will continue to buy under my account.
