NEDBANK PAYBACK MY SERVICE PROVIDERS

I GOT PAID ON THE 25TH SEP 2015 ALL MY DEBIT ORDERS WHENT OFF ON THE SAME DAY, ON THE 9TH OCTOBER 2015 ALL THOSE DEBITS WERE REVERSED OF WHICH NEDBANK IS SAYING THERE WAS A SYSTEM ERROR ON THEIR SIDE. TILLTODAY NEDBANK IS FAILING TO SORT OUT THIS MATTER, AND AS A RESULT OF THIS I AM ACCUMLATING INTEREST ON A DAILY BASIS FOR THOSE DEBITS THAT WERE RESVERSED BY NEDBANK SYSTEM. I'VE LOGGED CASES WITH THEM THEY HAVE REFERRED THE MATTER TO THEIR IT DEPARTMENT BUT ARE FAILING TO RESOLVE THE CASE. REF NO GIVEN ***1
