Simple Question: Can't you just call your credit card company and ask them to void all of these charges? My assumption is that credit card companies are obligated to take off any charge you deem is unfair. It is their responsibility to find a proof that charge was with your explicit agreement. This is why they get to keep 1-4% of each transaction in first place. Doing this also had side advantage that merchant ruins reputation and loose their ability to charge like this in future. Wouldn't this be the least hassle way? Just 5 minutes on call and charges are poof! gone.
