Gosh - you can be harsh ... in a storm the power may go off, but usually only for a few hours - not days. Can't really expect some old dude to live by candlelight, and have the food in his freezer go off, just because you don't want to pay weekend rates.
The PM didn't receive any calls ... did they call the office or the mobile? Do they have the mobile number, or is it given on an answering service if they dial the office?
I rang after hours last Friday as urgently trying to get in touch with my PM about a tenant issue ... was transferred thru to an answering service who took my details to get the "on call" agent to phone back ... it's now the following Thursday and I'm still waiting. Luckily I managed to track down a selling agents home number several hours later and they dealt with the issue instead.
