I think this letter asks the right questions and in sufficient detail to require specific answers rather than a generalised attempt to reassure or " waffle". The grammar needs polishing but otherwise it looks good to me.
Typically Mr Bowler's preferred response is to invite the writer to a meeting when he is polite and welcoming but rarely gives direct answers. It would be good if a written response was received to this email as it avoids the possibility of subsequent challenges to what was actually said at a meeting and the context in which it was said.
I think fans do deserve some straight answers and I wish you the best of luck.
