How did you pay AA? Was it with a check? So what you're saying here you sent them $2800, and you're getting nothing in return? Did you cancel the order of the tank? I live in Columbus, Ohio where AA is located, I've known lets call him RG for several years (not on a personal level, and know nothing of his business practices). I used to visit his shop fairly frequent many years ago, and was talking with him recently. I ended up buying a 110 off of one of his cohorts, who couldn't of been more fair and kind. Is there anything that you're seeking besides the $2800 back? I'm just trying to get a feel for the full story.....
