"Worst customer service ever"

I have been 2 months in arrears but have been committing to make my monthly installment every other month after falling into arrears, i have tried to negotiate some sort of an arrangement to pay off my arrears, i have then been told that new customers dont get to make arrangements, next thing i know i have a repo guy contacting me and coming to my house at 18:00pm on 2 occasions to try and get my vehicle, i have now managed to come up with R12099 after having to deal with much threats as if i am a ********, of which my arrears are R13068, i ask the repo guy whats the way forward if i am outstanding with R969, he tells me no arrangements if i dont pay the full amount they will uplift the vehicle, this is the worst financing house in the entire south africa, they have no remorse for you as a customer instead they treat you like a ********, i will be writing to the Ombudsman about this as the first installment missed was not my fault it was MFC debiting me on an account of mine that no longer exists, how do they get your banking details incorrect in the first place? this is totally ridiculous and if there was ever a time i could let people know what type of bank they dealing with it would be now, worst customer service ever, totally disappointed in my experience with this bank.
