In my humble opinion B+B are much better than KL and get more work BUT this kind of thing must happen all the time if they take so damn long to get back to people so it serves them right in a way that they lose kids they really want.
If they were so keen as they say to represent your DD, why did it take them a month to phone you? I know they are busy but so are all the agents yet B+B are they onl ones who takes weeks and weeks to reply.
Sorry I went into a little tantrum there!
Tough one for you, how have you found KL so far?
