Tradus — Taken payment but no product delivery

Address:

Durg, Chhattisgarh

On 28/02/2013 I had placed a order of Digital camera on TRADUS.com.And I had made payment by my DEBIT CARD(Rs.8130) on the same day.My Sub-Order ID: 7852314_01.And on my website account it displays that the order had been dispatched from the seller.(Blue Dart #[protected]).When I checked the courier website it shows that my order had been deliver to Chennai Some one Srikanth.Then I tried many numbers provided by tradus as there contact numbers.But on calling on this number they seems to be fake.No respond is given to my e-mails or complaints on tradus.
So I request you to help me to get my refund and any genuine contact number by Tradus .com.
