Kick up a fuss mate. In a fair, reasonable, 'no-I'm-not-a-nutter-but-this-is-NOT-good-enough' kind of way. Ask questions and see what they have to say, give them a chance to explain things, but mention reporting them if you're not satisfied with answers they provide. It sounds like they might need a bit of a wake-up call.

It could have just been a bad day at the centre, bad communication, and chaos, but that kind of thing regularly isn't acceptable. Hope it's not as bad as you think, and they have a good and satisfying explanation.
