Auction issues
I feel your pain, for real. I posted a thread about a bayonet I bought off eBay that was completely misrepresented. It took me a month to force the seller to take it back, and only then when eBay stepped in. I had to take pictures and compare them to the description that was provided in the auction.
At first I thought it might be an honest mistake, but then the seller reposted it, and completely avoided the details that I highlighted when I returned it. In fact, he used language designed to avoid the truth about his bayonet. I had no way to warn the prospective buyers. I had to sit by and watch another misled collector bid more than twice what the bayonet is worth. I am sure he will return it also.
If I fail to read the auction correctly, or fail to ask the correct questions, I accept my mistake and move on. And there have been a few, for sure.
If the description is incorrect, or I ask a question and the answer is not accurate, it goes back. I have returned two in the 4+ years I have been collecting.
