I had a much different experience when dealing with Neil/TNK than what the OP describes.
I'm a big fan of Winkler knives, particularly the Belt Knife. Some months ago I noticed on his site that he had a couple of Winkler BK's for sale with a different grind to the swedge than what is normally seen, a much deeper grind.
I called TNK and a lady answered the phone, I told her I had a few questions about the BK's and she informed me that Neil would be the one too answer my questions. She told me that unfortunately he was currently out of the office and would call me back within an hour. Roughly 10 minutes later Neil called from what I believe was his personal cell phone, credit to the lady for passing the information along so quickly.
Neil was courteous and professional throughout the entire conversation, took the time too answer my many questions and even a little chit chat that had nothing too do with my order... assured me the knives I would be receiving would be the ones pictured with the deeper grind.
Since I couldn't make up my mind which BK I wanted, I told him that I would go ahead and take both. When I inquired about his shipping options, he told me not to worry about that, he would be shipping both knives overnight at no cost to myself... doesn't get any better than that and both knives were delivered the next day as he said.
Neil/TNK is more than good to go in my opinion, I would not hesitate to order from him again.
