invies.com took payment and never shipped; fake reviews to seem less shady Internet

I ordered a robotic vacuum cleaner from invies.com for $49.00 (one tenth it's price on Amazon). Their website advertised to accept credit cards, however after entering your information they send instructions on how to pay them with a $50 Playstation code purchased on Amazon. I was skeptical, of course, and I did some checking before I followed through on the order and found several question or review sites  (yahoo answers is the one that fooled me) with reviews that weren't obvious plants--mentioning it took them a while to process their order but that it was a legit site for cheap merchandise if you can look past the poor service... Well those reviews were fake, and now you can find 50 to the contrary on yahoo answers. Do not order from invies.com. My order was supposedly shipped at the end of November to arrive by Dec. 8. I have no robot vacuum, and invies is not acknowledging attempts to contact them. Stay far, far away.
