With all the trouble people have had I'm surprised some regulatory agency hasn't stepped in and begun an investigation. I read one post at, I think the third link, where a person hadn't charged anything on the credit card but was being billed all the same.
Out of all the posts I read from the first three links, there were no more than two who chided people for misusing their credit cards, saying they'd never had any problems with their credit cards. Sorry, but when as many people as are on the first three links report problems of this kind, something is really wrong.
If something gets your goat, it just proves you have a goat to get.
