Wost customer service ever

I bought a taxi from them in Nov 2016 and have been paying well till September 2017 and I called them making arrangements to settle the account, I made an arrangement with one consultant and few minutes later a guy called swearing at me that if I don't pay he is processing with legal action, on the 30 11/2017 I went to the offices to make same arrangement and help by the lady name Mabotho who was very professional and logged the arrangement on the system. An hour later the very same rude and unprofessional guy called again saying that the does not care about any arrangement if I don't pay in two hours he is collecting the car, I feel so not value by your company with not values that guide your operation
