Lax in refunding duplicate debit order

To my dismay I noticed yesterday 31 October 2017 that the debit order to Capitec Bank from FNB has been generated again. The first one was done successfully on 26 October 2017 as per normal. I contacted Capitec Bank and was transferred from one person to another and the answers were very unsatisfactory regarding the reversal of this transcation. In fact it was clear that the staffmembers I spoke to heard the rumour of the extra debit orders but they were not informed about how it will be corrected. The one told me it will be fixed within 24 hours. Since it was NOT corrected this morning 1 November 2017 I called Capitec again and this time made sure I received a ref and was promised my case will be escalated to the department doing the reversals. This now four hours later and no telefone call or any other form of communication was received. This is really poor service.
