Bad experience with rental agent

I would like to understand, why Seeff didn't have any customer training, I enquired about a property on Tuesday, the gentleman phoned me back, I told him that I will spoke to the family and contact him back on Wednesday morning, he then phoned me back on Tuesday night just before 8, I missed the call, received a sms stating this "Hi there tried calling you regarding your query on rental available in Witfield at R7800 but rang to voicemail.

I then called him back and arranged to view the property, took my email address and never email, rep**** to sms to please confirm email address, no response, I then tried to call him whole day yesterday and still no response, I then had a problem yesterday after work and couldn't answer my phone, I then received this rude message from the gentleman "I have no idea how I can confirm this appointment if you refuse to answer your phone" and this message "Please don't contact me again killing the call everytime I call you is particularly rude" how the hectic can you tell someone this, I could have been in a accident and then receive a message like this.

The number that I received this ***.

He is very rude and I will never contacted him again, I don't even know what his name is or what branch he works at
