WalkFit Formerly Phase4 Fraudulent use of my credit card Internet, Internet

Before being invoiced and after providing my personal information, including my credit card info, this website immediately charged my card.  I immediately contacted them via email (no phone available!) and told them in writing that I did NOT approve the use of my card and that I had no idea what the total proposed charge even was.  Customer service wrote back with the total amount and told me they could not cancel because they were already fulfilling the order.  I was told I could reject the package upon arrival and that they would return part of my funds but not the 15$ shipping and handling.  This is an outrageous, fraudulent business that should NOT be permitted to scam people of their money like this!
