Serious unprofessionalism

I called Nicholas Buthelezi and made an appointment for 4pm to view a house. I called numerous times from 3.45 to get the exact address but he ignored my calls. My husband then called him with a different number and to my surprise he answered the phone . How unprofessional. What happened to honest communication and honest business practices. He told my husband that he was not even in the area but would call him back in a few minutes after finding out if the keys are available but he never did. My husband tried calling him but he started ignoring him again. He could have just called me earlier on and canceled the appointment if he knew he wasn't going to make it or tell me that the house is no longer available if that was the case.
