Interestingly, disputing a charge is one thing, but reporting it as fraud when one made the purchase is, well, fraud itself. I just assumed the OP intended to say he would dispute the charge.
Disputing a charge should be a last resort, people like the OP are why I charge more selling things in the classifieds. I have offered discounts for unsecured payment methods in the past, but idiots ask for the discount price and to just pay the much smaller CC fee, because I guess some people are too stupid to read what is written in plan English, so now I just ask for enough to be worth my trouble. I'd literally rather throw a few hundred dollars away than have to deal with a jackass. Ok, thread jack and rant over.
