I mentioned apartment issues earlier and there were many. Things were either not functional when we got the keys or would easily break on us

I had a date with Mary, but she cancelled on me.
Cambridge Dictionary gives the 'faulty thing, machine or gadget' meaning, but, at least in the UK, a person can be talked about in this way if they unexpectedly fail to do something expected or promised:
