Sometimes our forum has a mob mentality and once the mob forms, the piling on begins. Actually, this phenomenon is not exclusive to our forum by any means, but is a psychological trait of the human condition...lol!
If I might add a piece of constructive observation, several of your posts in this thread certainly poured fuel on the mob's proverbial fire...lol!
I don't like having to chase payment either, especially over several attempts, but I also recognize when a MSC owner or executive offers an olive branch my way as B.Eason has done for you. It's never too late to step back from the edge of anger and accept the best outcome for this situation. Being a cancer survivor, you have certainly faced much more serious issues than this one. Accept the olive branch, provide the documentation requested, get your fees refunded, and move on to more pleasant endeavors...after all, life is way too short to sweat the small stuff!
Just my humble opinion as always...
