BDA — EMD 4 lakh not returning

Address:

Bangalore, Karnataka

My name is Karthikeyan S. I recently applied for e-auction and paid 4 lakh INR TO BDA BANGALORE COMMISSIONER via online banking. It's been 2 weeks since the money has been deposited. i lost the bid, however BDA is not returning or refunding my money back. I wonder why it should take so long to return the money . When i call e procurement, they give some telephone numbers which no body picks. I am not sure what to do now. Please help.
