For those who haven’t read or at least understood what the OP has put down, he has not yet been “Barred” he has been “excluded” until the Commitee meet and discuss.
As someone else who was trying to be helpful said, write to the Head of the Committee and put things down as you see them, ask to be present when the matter is discussed/decided on.
TBH – the only people who really know what happened are those that were there at the times. I have to agree with others that there is more going on than you are letting on or that you are aware of. I sight the comment “I may have my moments but never in there”. So do these “moments” happen when you are in a room all alone? Or do you have a “rep” that people in the club are aware of and have expressed concern about? I assume that the other people in the club live in a similar area to you/your parents so to a degree rightly or wrongly they will probably have some opinion of you. It could be totally “wrong” but if enough people express a negative view of your self I suspect you’re shafted fella.
AS for getting fees back, again as said read the regulations and you’ll probably find that the Committee can decide to ban any member with no obligation to return fees paid.
My gut feeling is that you should really be honest with yourself about this whole affair.
