Back in 2006 as a noob I bought what was advertised and shown as authentic Green Irish Tweed from an eBay seller from NYC with a 100+ transaction and 98% Positive Feedback. What I got was a 4 oz bottle of waterish and somewhat foul smelling crap named on the Creed knockoff bottle 'Green Irish Frick'. Seriously.
I immediately contacted the seller and threatened legal action through USPS fraud law. He credited my AMEX account after blackmailing me, threatening 'I will post your first Negative Feedback" and'forcing' an agreement I would not give him a Negative Feedback and that I sent the crap back to him. Then, a couple of weeks later I saw he was offering (presumably) my returned bottle again on eBay, showing a legit bottle of GIT of course. It was then I left him Negative Feedback outlining my experience in a few words.
He retaliated by sending me a few threatening emails and posting a Negative Feedback saying I never paid for or returned the "legitimate bottle of GIT" he had sent. eBay allowed and by doing so encouraged that kind of retaliatory action by fraudulent sellers back then.
I posted a reply giving the AMEX transaction number of my payment, adding a few words to avoid this crook at all costs. I then sent a letter with all pertinent info to the USPS, the NYC PD, the NYC Attorney General, eBay, AMEX, the Creed authorities in the US and posted on Basenotes of my transaction with that noxious turd. Of course nothing was done about it through legal channels but he did stop selling under the eBay name he had used with me and, I suppose, just continued by creating another eBay name and address.
I would like nothing better than to meet up with that crud in a back alley sometime.
