emummy It is massively frustrating, especially when you know people have got in in previous years with similar results. But you have the advantage that you can start phoning round at 8am on the 13th before the A level students have gathered their thoughts.
My daughter was in a similar situation last year. Based on her experience I would say start with Dundee, use more than one phone, and hang on the line until someone answers (it may take 40 minutes, the line may go silent, but if it's not dead, don't hang up!).
