PA31,
What u can do is complain to the head of ASL- ring CASA for his name.
I meant to sit an exam several months back, I travelled 3 hours to the exam center only to be told that the exam venue was unavailable. The supervisor had not made any arrangements.
I saw red and was able to scum a free exam off them for my trouble. Moral of the story, give ASL grief, stir them up, and they will eventually listen.
GA has no hint of customer service on the whole!!
