Emergency maintenance is a joke

So I live in a complex that states on its website "24 hours on site emergency maintenance". Last night my refrigerator was making all sorts of weird whirring noises and I was afraid it was going to either overheat and start a fire or stop working entirely and I'd like all my food. I called emergency maintenance roughly ten times between 6 pm and 10 pm and nobody ever picked up. I finally gave up and called my brother in law who came over around 11, pulled it away from the wall, banged on some stuff and it sounded better. I intend to go over to the office today and tell them about what happened. But I'm very annoyed. If this had been a broken pipe or an overflowing toilet or another legit emergency and I can't reach anybody, what the hell am I supposed to do?
