Can't believe how prevalent this is. I just started to post stuff and have it experienced it myself whether I am buying or selling and wanted to see if it was happening to anyone else!
@Oscar there's not much more you can do without being rude yourself and jeopardizing your own account. I like the way you handled it! I'll try some of your methods the next time I have to deal with one of these bozos, which should be any minute now. Good luck, see you around the forum.
