Myntra.com — someone hacked my account and used my myntra credits. now I'm locked out of my account.

Address:

Hyderabad, Telangana, 500032

I noticed that some random orders were placed from my account and my myntra credits were used. After contacting the customer care twice, i was told that the order which was in "packed" status will be cancelled.in order to check the status of refund, i tried logging in my account but it says that my account has been locked. Moreover, the password and the registered mobile number of my account has also been changed. Customer support hasn't helped me yet regarding this issue.
