ABSA bank ********* behavior/system behavior negatively effecting my credit score

ABSA internal system either did not initiate and/ or initiate debit orders on dates that I did not agree to. Resulting in there being inefficient funds because its early before before my pension pays in or the funds were used otherwise. Life is expensive. The overall implication is that this has negatively effect my credit record with ABSA it self and with other banking institutions. None of this was initiated or controlled by me and is due to a system fault of internally of ABSA. BUT they thought it good to report this as non payment. I have ALWAYS paid all my debt and the bank due to a system error decline a life a death increase in credit card limit due to this. I have repeatedly called to confirm the debit order date of the loan amounts, but every time they say its correct on the system, come month end then it goes of my account 2 - 3 days before my pension comes in. It think it is shocking how the mistake made by the bank should effect MY CREDIT records in ANY WAY. I have tried to resolve this impact on my credit record repeatedly with them but they just don't care that this impacted me negatively due to them making a mistake. They get there payment or take double payments when they then so please to catch-up. It is totally unexceptional that this this can and should be allowed to occur.
