MFC account supposedly in arrears, two days after paying.

This morning I received a call from MFC Call center , Gertrude Ledwaba - she was calling with regards to my Motor Vehicle finance account that was in arrears for the 2 DAYS of the month of August - My payday is the 26th - Payment was made on the 26th of August - over and above the installment amount. After I was completely taken aback at this ridiculous call regarding an arrears amount that I know I had paid 2 days before. I asked her to make sure she had the right information because it was already paid -she told me hold on so she can check - mins later she confirmed it was showing on their statement but not my account hence why she called me because they system told her my account is in arrears - Really MFC - don't you do recons ? Why is my account not updated on time? Why should I get such ridiculous calls two days after my payday ?? Why are your system issues your customers problem? and No, Gertrude, it is not OK ....its never OK!!
