to attempt to tell everyone else not to buy from them because they will get scammed like you feel you did sounds ridiculous
If we made a list of all consumer products companies out there, then removed from that list every company that someone has had a bad experience with, we'd have a blank piece of paper.
There's a big difference between a "FYI everyone, I had a problem with company XYZ, here's what happened..." posting and a histrionic "XYZ company is a scam, nobody ever order from them again!!!!!" one.
