Perfectio zero gravity Selling a fake product made in china. Miami

A couple of years ago I was at a trade show, and there was a stall selling Perfectio zero gravity , which is basically a red light therapy with heat, which are selling with other companies for a $100-$200, now, this company Zero gravity based in Miami are selling it for $4500!! However, they sold one to me for $2500 and gave me one free told me I can sell it to make my money back, after talking to a number of people that have been to the beauty trade shows, same happened to them, After 2 weeks I called them told them I want a refund as there product was fake, and did not work, this is a product that's made in China! Like most are for couple hundred, they have NO scientific proof it works, only by what there website states which is not a proven track history. I sent my perfectio back both of them ,only for it to be returned, I have all proof and conversations, I even told leah who was running the company it was fake and I'll go to social media to make people aware, I still have the products when they were returned to me, I ask them to pay for me to resend and they did not. So, my question is ,IF Perfectio was so good and expensive, WHY would they sell one and give one for free??!! Think about it, now, other people who bought one from trade shows were given one for free are selling the second one. perfectio has NO proven track record NOR have they mentioned who designed the product. They are ripping people off!
