Rude Agent

I would like to complain about an agent(Shaun Nagish) whom called me regarding my car whom was very rude with.I received the call today.He said I have no right to complain about anything since I'm owning MFC however I find it hard to believe that as I'm still a client/customer at MFC division which by consumer act I have some sort of rights.When I explained to him that I'm not working I get no salary I'm self-employed he called me a ****.He accused me being rude with the previous call center agents the last time I engaged with Thembelinhle Madlolo I dont remember us going into an argument about me making arrangements on my account.This guy didnt want to listen to anything I had to say said I have no right to complain and treathen me that my vehicle will be repossed if as I'm in arrears.When I tried to explain to him I'm waiting for a client to pay as they have promised by the end of the week.He carried on with his threats.As my business is still a start up cash flow is a problem and I'm trying my level best for someone to tell me I have no rights to say anything as I'm two months in arrears.

I'm not sure that's how MFC agents suppose to address me as I'm a client in arrears but I believe somehow I'm entitled to some sort of respect from the agents not to be belittled like Shaun just did now.I'm not refusing to pay the car but this kind of behaviour I find it unprofessional.Being in debt that does not make me a ******** and gives no one to treat me the way this Shaun just did
