Tradus — Not refunding money

Address:

Ghaziabad, Uttar Pradesh

I ordered "Inalsa Multimix Hand Blender" from "tradus.in" with transaction id 2439733 on 8-Apr-2012. When product was not delivered in 7 days I cancelled the order on 15-Apr-2012. Since then I am waiting for refund of my money. They promised to transfer it in 10 days however even after sending lots of mails I have not yet received my money. In my last mail I was promised to get the money in 24~48 hours but even after three days I have not received anything. Now they are aging asking for 3 days.
I guess they want me to file an FIR against tradus and ibibo group.
