If not, I would make them aware of it. They might put some pressure on this POS.
Next if this loser advertises accepting credit cards, you might want to call up the card companies and inform them he is really NOT accepting their cards.
Next if you have a BBB in your area, make sure to file a complaint. It can't hurt and in some cases you actually get a refund pretty quick.
Finally keep adding info here on a regular basis. This gets the word out to MORE PEOPLE.
Isn't the internet great?
Oh yeah- sooner or later this will be over. When it is, you have the option of vandalizing his business, his personal vehicles and whatever. You can even follow him home. Also you can post his personal info here for other people that might want to "phuckk" with him, if ya know what I mean.
Good Luck!
