Worst service ever expirienced.

I had a contract with cartrack for two years I lost my job I called them to let them know of my situation after that I got a call every month sometimes 3 times or more. All the time it's different agents, i made an arrangement to pay them R100 monthly I still got calls every month requesting me to pay which was annoying because I was honouring my arrangements today I got a call from attorneys saying my account has been handed while I have honoured my arrangement. This company has a very *********** accounts department. I will never do business with them I know I am a drop in the sea to them. I have never experienced such a pathetic customer service.
