Call center Lady Call Client a Know it all

I was called by one of the call center Ladies about payment of my wife's account. When I told her that I cannot afford to pay more than the money I am currently paying she started threatening me. I asked her to make sure that they have the correct address on the system to ensure if any legal docs or Summons are sent to my wife that we would get the documents so that we can defend ourselves in court. when I asked her Name she Called me a know it all. I then asked her over and over for her name and she just put the call down. <br> I feel it is unacceptable for someone to be rude with me and to threaten me. I was not rude with the lady. I just explained to her that I can only afford the amount that I am currently paying and if she wants to threaten me with my house then we can go to court. My wife may owe money to Standard Bank but there is no reason to call people names.
