Andre's bad work ethics and professionalism

Friday 20th I requested to view a rental property in Sandton that I had an interest in. I spoke with Andre. He asks what time I'd like to view for the following day, and I propose 10:30am. He tells me he can only do 11am, so I agree for 11am. He then sends me a message at night that we'll have to move the viewing to 12:30pm as his principal wants to meet him on Saturday at 11am. So I tell him I'll have a meeting at 12pm, and I'll be available on Sunday. I then text him again Saturday asking if he's available because my Saturday meeting wrapped up quickly, and he sets up our viewing for 3pm Saturday. While I waited for him the whole Saturday afternoon, he calls exactly at 3pm saying he won't make it. I then reprimand him about his professionalism since I postponed my family outing to meet him. Instead of apologizing he shouts at me that I can't talk about his professionalism and that he won't give me a chance to talk on the call.

This behavior is barbaric and intolerable, Andre doesn't RESPECT other people's time and I will review this company all over social media until he apologizes for his actions.
