Roduve Slimweight Patch Paid for it but never recieved the product !! Internet, Internet

I paid for the slimweight patches from Roduve on the 8th of April 2012 but never got the product. When I contacted them, they replied saying ".....out of stock.... will ship soon as it is in stock..." etc etc. Since I had to use my credit card, it's incurred high interest on that payment as it's an oversees payment for me; not to mention the oversees payment fees on top of that as well !! Well, I live in Australia. The way it is explained about the product on their website, I's given the impression that it's delivered immediately and soon as I get it, I could cherish the outcome of such miraculous patch!! I wonder how many of others have fallen victim for such kind of scam!! Please, who ever is thinking of buying this product from them, make sure you clarify all possible excuses before you make any payment to them. e.g.
> Is the item available in stock or not?
> How long will it take for shipment?
> What is the refund policy? Is it from the day of purchase, or from the day of receiving the product?
   (...as overseas deliveries could take over a month since purchased!)
etc... etc....
