Tradus / 16 Gb Pendrive — No refund

Address:

Gwalior, Madhya Pradesh

Dear Sir,

I ordered 02 nos of 16 GB pen drives @ Rs 499 each on 01 May 2012 and transferred money via net banking. I did not receive shipment. I enquired from Tradus they told that my place of delivery is out of service area of their courier and they will refund money as soon they get conformation from supplier about return package. Till date no refund is received from them. I thing they are cheating. What should I do?
