the deal empire took my money did not deliver goods will not reply to emails Internet

I saw an advert on face book for these miracle pants that flatten your tummy, there was even a video showing the results, so I decided to purchase them for $21.91 including postage, three weeks ago, my order said it would be dispatched within 72 hours,

As i have not yet received my goods I emailed them, I had no response so I emailed them again 3 days later, still no response.

I cant get a tracking number or refund, so dont know what to do next.

I have now seen other reports of the same complaint.
