Irresponsible behaviour

I have made an offer to purchase an apartment on my roof. I had given all my contact details to the website and to the agent requested by the bank to process the offer. Ms Ntsoaki Mokaleng called my office and my PA informed her I was at a meeting and that if she left her details I will return her call. Instead she emailed the agent saying I cannot be contacted. I obtained her details and called her to give her the information she requested and inquired why did she not leave her contact details for me to call her back instead of having to trace her through a third person.. She screamed at me asking me what my problem was and why was contacting the agent a problem. She was practically abusive. I had to calm her by telling her she was being recorded. Surely you cannot have people like this dealing with customers. I was so put off that I did not want to pursue the loan anymore and offerred to pay cash for the property. This woman need to be moved to a post where she does not deal with the public.
