KFC handed my account

Hi I really need clarity..i have received a call a day ago informing me that my car account has been handed over and need to settle the amount of R5300 before the end of business day tomorrow..Im under debt review and missed one payment for the month of August.but then the on September everything was back to normal.i feel they did not communicate with me to make arrangements and also the company they handing me over too is not willing to give me notice to pay the outstanding amount..i think one day is too little to arrange payment and also for MFC to terminate the debtreview is so unfair cause I only missed one month not several months.we could have arrange payment which I'm sure I would have paid as I'm also willing to pay the R5300 by end this month which I also don't understand how it went to that amount.
