Hour one: who receives the report
The first question is where a report actually lands. A mobile number belonging to the cleaner is fast but stops working when that person is on leave. A general office line is reliable during business hours and useless at seven in the evening. A monitored email address sits somewhere between. None of these is wrong, but you should know which one you are being given and what its limits are.
Ask what acknowledgement you should expect and within what time. An acknowledgement is not a fix, and saying so plainly is more useful than implying an immediate resolution. What you are testing is whether the provider has thought about the difference between receiving a message and doing something about it, because most unresolved complaints stall at exactly that point and the reporter assumes silence means nothing is happening.
