[Resolved]  Flipkart — flipkart account hacked incident no in[protected]

Someone hacked my flipkart account and 1st reset the password, then he changed the email and and after that mobile no. It happend on 16th nov 2018 @ 2.44 pm. I complaoned immediately to flipkart. Today is 27th nov 2018. Still they are unable to track hacker. Very poor security system. I have mobile no which is updated in my account. Still flipkart is unable to do anything
I have provided ladt invoices, my billing address al required details for verification. But still very poor security system to catch the hacker. I can not understand how someone can reset password so easily.
