Acostmall Ripped off by Acostmall! Internet

 I ordered an air floss from Acostmall on August 21. 2013 and they said it would arrive by Sept. 3rd or 4th. Well it hasn't arrived and after reading the other complaints about this company, I doubt that I will ever receive it. They also made me go through Amazon and it showed up as a "game card" so that no tax would have to be paid. That's a rip off right there, isn't it???? Not only that, but they charged my card twice and I had to have my bank step in to clear up the second charge! The $50.00 they wanted for the air floss was 1/2 price every where else on the internet. I guess that I should have known that it was too good a deal to be true. What happens now?
