This is exactly what I've (stupidly) been doing. Irritating in the extreme.

Sorry to hear that, you just have to take control back really, until booking is confirmed no body is obliged to wait around, unless there is only one for you, then you are screwed.
Just consider an email to them the same as getting an insurance or building quote, you don't wait for them to get back to you without messaging the next. Its not an audition or job interview, its a punt.
Good luck getting out of the circus, sure the RSPCA will help !
