I've just phoned the managing agent again and it seems and it seems he's not happy with the work either. He says they aren't getting paid until the walls and some other work is finished properly. But I bet they won't knock the worst of the work down and rebuild it, probably just add to the over all look of botch-up they've already achieved. Should be interesting to see what happens next.
I must sound really pessimistic... I'm not it's just I'm a very experienced optimist
