There's nothing wrong with that eBay auction. I've never heard of an auction getting messed up the way you describe. This looks like a very simple case of Back-Woodsman. Now, not to get people in a huff, but look at the seller's location. That would be enough said..
Seriously though... This was NOT a reserve auction. The seller just wrote that the item had a reserve in the description. This doesn't count.. That was his own mental reserve, not entered into the eBay listing form. According to eBay rules, if the item sells, then it sells. You can't write a disclaimer in the description to put a false reserve on it.
Filing a negative is only part of what you should do. Now you should also file a formal complaint with eBay. If you go to the auction page you should find a BUYER's link that takes you to info on how to do this. Someone only needs a few strikes like this to get their account suspended or cancelled.
If the seller wanted a reserve he should have input a reserve value into eBay - which costs extra $$ if it's not met and the item doesn't sell. ANd if he wanted people to know his reserve then he should just have started the auction at $600. That's how it works. The only purpose of a "hidden" reserve is to get people into a bidding frenzy and build hits and re-visits for the auction.
