@Linkat,
Offhand, it sounds like fraud, but it's hard to be sure. I once ordered something from a business in Florida, or somewhere like that. When I got the credit card statement, there was my charge, but the vendor was a Radio Shack in Arizona. It was a legitimate charge, but it sure got my attention.
Good for filing the dispute. Since you are in business, I'm sure you recorded the date and name of the person you spoke to.
