Threaten to Repo due to Absa mistake on DebitOrder

I was employed by Absa for 3 years until end of Jan'15. Being staff of Absa, the AVAF (Absa Vehicle Finance) debit order went off from our Salary (Pay slip). In Jan'15 I called AVAF to inform them that I am moving to a new employer and that the Debit order must go off from my Cheque account on the last day of each month. I was able to confirm the changes by going on Absa online and viewing the account info.<br> <br> I got a call at the start of May to tell me that I have missed a payment, and that I must make a plan to repay it. This was the payment for Mar'15, and by this time the debit order did go off for April'15. I explained to them that I have arranged the debit order to go off from my Cheque account back in Jan'15 and that I am not able to pay back the missed installment due to me using the money that I have left in my account after the end of the month. They declined my request to reage the account<br> <br> A few days later I got a call to inform me that he can give me a few days to do the payment or he must repo my car.<br> <br> I am highly disgusted as I have never missed an installment in 3 years being an AVAF client, and the missed payment was Absa's mistake as I had money in my account
