minutedownload.com charged credit card and did not give download or product keys Washington District of Columbia

I bought a Windows OS from minutedownload.com: all went well at the checkout, and I received (what I thought to be) a $5 coupon using the code "5offnow". After I paid for the software, I was taken to a screen that said "checkout complete, please wait while we process your order".  

I waited over an hour and the page did not refresh nor did they email me a download link or product activation key. I called tech support 3-4 times and was told "their office was closed" and to call back during normal business hours, even though I was calling during those times. I sent 3 emails to their tech support and never heard back. Their chat either does not work or they do not check it: they have not responded to the several chat messages I sent requesting assistance.

Its been 24 hours since I purchased the software and I have not received any feedback. I am pretty sure the website is a scam-- Do NOT buy anything from it!
