Flipkart — Flipkart account hacked by stranger

My flikart account got hacked by some stranger and I am unable to access yo my account and the hacker is utilizing my gift voucher money by placing some orders through my account.
I tried reaching out flipkart customer support for dozens of time, asked to help me get my account back or disable it untill my issue get resolved but nothing worked out. It has been three days now since I am getting this issue and no help from flipkart yet.
