I responded to a Facebook page that was offering Oakley sunglasses at a discount. After purchase, and an invoice emailed to me I noticed that my credit card was actually charged more than the invoice was and what I was to be billed. That was my first clue that the transaction was not legitimate.
I emailed the company by returning the email that was sent with my invoice. I asked for the shipping information and tracking information that was promised on their website with no replies. There are no phone numbers or addresses listed but my credit card showed a company from China had charged my card, so at this point I know I was scammed.
I have since put in a dispute with my credit card company and will forward this website to all that I know so that no one else gets scammed.
