Bangalore Development Authority [Bda] — BDA E AUCTION - EMD Refund issue

I participated BDA e-auction and paid INR 4 lakh EMD per site TO BDA BANGALORE COMMISSIONER via online banking, I participated in 4 different sites, total 16Lakh EMD not refunded.
i lost the bid for all 4 sites 11 days back, however BDA is not returning/refunding my hard earned money.

I call e-procurement, they asked me to call BDA, I tried reaching BDA mulltiple times but no luck. finally i sent an email to "[protected]@bdabangalore.org" and "[protected]@ka.gov.in" but no reply yet.

Need help to get my EMD back, It seems no one is responsible for EMD REFUND AT BDA.
