very rude on calls

Ive had several heated discussions with amanda from your pinetown branch. She really does not know how to speak to clients. Last month she called me cause i had issues with my bank account which resulted in my payment being late. I asked her to notify the owner of the flat and she said fine. What she did was to tell the owner a lie and she asked him to kick me out.the owner is my friend and he told me when i asked Amanda why she told the owner a lie as to why my rent was late she told me \u shud mind yo own **** business and shut up". I asked her is this how u always speak to clients and she said yes. I told if she does not stop yelling at me i will log a complaint and her response was Fine go ahead see if i care. I told that m your client please can you treat me with respect and she told me \""oh shut up and go to hell\"". As mentioned this is not the 1st time this has happened and the owner my friend is even thinking of moving his business since this iss how his tenents are being treated. Please can someone address this matter urgently and i would like a written apology from Amanda regarding her rude ways last month? She is based at yo westville office 2 church road westville."""
