I would switch distributers. I have had many replacement parts on my NIB games over the years and was never,ever charged a cent. Only thing I had to pay for was return shipping on items that they wanted back. Tell him stick his 100 up his a$$
Best part is the way it works from stern is they charge your dist. the price on item until you ship them back then they credit his account.
He screwed ya out of an extra 100 for his trouble.
