I don't know if you know the phrase Graham, but in the mining industry here in Aus, it's called, been given the 'Window seat'. No warning even when you turn up at the airport for a FIFO, there's is no ticket waiting for you - Shafted.
There is no excuse, ever for this sort of behavior, especially since they pulled other tools as well before the deadline and I woke up with this at 6am on a Friday morning much the same as you did. I am not a Betsi subscriber, but this tactic is disgusting, and like many others, well I have quite a few words, but they shouldn't be repeated.
This is a tune that is keeping me going at the moment.
