Myntra.com — hacked

My account was hacked. 30+ accounts are connected to my email i'd. I prevented the hacker from making a purchase with my credit, but the hacker called customer service from another number and transferred the credit to his account and deactivated my account.in spite of me warning myntra on the hack, no security measures were put in place.

I want my credit of 5k back which i lost due to myntra's lack of security measures.
