Communication gap, Bad service, Lack of Interest

Good day, I Charl Celliers phoned yesterday and spoke to Jolanda or Jolandi, can't remember. The reason I phoned was because of my account CELL00028. Ja I know it is in arrears but as I explained how many time, I am unemployed. Yesterday I got a message which said my account will be handed over and I will be blacklisted. I phoned, spoke to Jolanda/Jolandi and she said to me the person working with my account is Petronella. She will notify her that she must phone me in connection with my account because I explained everything to her. Right, I have spoken to Petronella some time ago and I did say to her that I'm unemployed and is there a change that I can pay of the arrears amount. With that question she answered and said yes, she will make a notice about that and update it on the system. Last month I made a payment towards the arrears amount, but yesterday I got a threating message which stated I will be blacklisted. Now, Is there a communication gap at Cartrack or what the hell is going on. This is the worsted service I've ever had and is frankly fed up with it. Please call me back and answer my questions ASAP?
