I've hung up on a few more than that, but always with good reason.
I hung up on the manager next door on Thurs.
The house we're moving to is in the management system next door so all expenses related to the rehab get billed to that park. He is a lying, manipulative, bullying asshole. On the phone he straight out told me my maintenance guy didn't want to build the counters that I wanted for the kitchen (which was a lot less expensive than custom ordering them). My maintenance guy was standing right next to me and he never said that.
Later he asked my guy what size dumpster they needed for "that piece of shit house". Plus he tried to trash talk me but my guy shut him down.
What should be a simple renovation i.e., new floors, countertop, 2 showers, 1 vanity, 1 vanity top and paint has now been completely soured and is stressing me out.
Every single one of my maintenance staff plus the staff next door is ready to quit. The residents all hate him. I have no respect for him. Also found out he's been arrested for domestic violence (hitting his adult daughter) more than once.) Why he is still employed I have no idea.
Hanging up on him is a pleasure.
