I am still a client, do not BULLY me ABSA

I appreciate that I have arrears that amount to 2 months for my Absa vehicle finance. I recently had financial obligations which I am recovering from. I made an arrangement to pay an additional R 3, 200-00 on my account for the next 2 months (and am still willing to do that manually since the additional amount was not deducted off my account with the original debit order). I got a call this morning from "Absa", you never who is calling you on behalf of the company now, demanding the "full" amount TODAY OR THEY TAKE THE CAR TODAY. If I had it (the amount) I would have paid it immediately, since I do not have it TODAY I still expect Absa, as per my contract to notify me in writing of such action and give me the "allocated" time to sort out my financial affairs with them. The gentlemen who called me this morning first ask "When can you make the payment", upon answering trying to give him an answer he quickly jumped to "I am not giving you an option, I want it now, if you told me you would pay tomorrow I would listen", why did he ask me in the first place. I feel I am being bul****, of course Absa is bigger than me.
