Heartless Consultants and bad treatment

I am really fed up by the treatment from their consultants, their behaviour is like they were trained to be evil, they don't want to hear your point. They only thing they are good at it's to threaten that they are going take the car. It's like they don't live on this planet. It's like they don't have debts in their lives. Their treatment is now irritating, they have a evil way to treat their customers. I am aware that account is on arrears and I am making sure that every month I pay the normal installment plus arrears but they keep threatening me every month that they will repossess the car. My arrears is R2800, then I requested to pay R1100 extra because is the amount I know that I can afford but they are refusing and that stubborn consultant told me that they are going to take the car if I don't pay half of that amount. The account is paid every month plus normal installment but they keep threatening that they will repossess the car, what kind of madness is that? I really hate it when someone tries to take advantage of me. I regret buying from this bank, I will never recommend anyone to buy through MFC. Most of their consultants are heartless.
