All is not lost sweetie and I'm going to tell u why: First of all do you have the bill of sale? Reps name? their business card? YOu can get all your money back but its going to take some time. You MUST report this company to the better business bureau and the case worker will do a background check to find out whats what. Once they are tracked down, go to small claims court and file a suit against them.
Thats just too much money to let go and not take action.
Don't be embarrassed. Sometimes when we get excited we don't think with a clear conscience. We get so gung ho without taking a step back to see if there's anything shady about the deal. Happened to me when I bought my first car.
This will teach you to be a better shopper and to make wiser decisions.
