Salvage world auction Marcos Santana[sales rep] Promised $10000 refund but not given Miami Nationwide

I brought a 2015 Mustang convertible on the 21of of June from Salvage world auctions from a rep called Marcos Santana, I paid via bank wire transfer after three weeks of calling the car did not arrive no explanation of where or what happened to it .

So I asked for my $9,600 dollars to be refunded i called and emailed all that was requested of me and for a three weeks they have kept stalling by saying someone would get back to me but this did not happen .

This morning I was told by email that they had made a mistake and I would have to buy another car or wait 90 days for my refund .

So what they have done is to advertise and sell me a car they did not own take $9600 dollars via wire transfer kept my money and are trying to force me in to buying another car
