Accounts department

So I phoned them to change the bank from where my debit order is taken from FNB to ABSA at beginning September 2020 and spoke to Sheila. Come end September when the debit order is due, it still goes of FNB, but suddenly there is another Car track debit order going off my ABSA account. I then phoned and spoke to another person (Katlego) at the end of September who informed me that she saw the request for the change but it was not actioned and that she would fix it. Come October when my debit is due, I only have an amount going of my ABSA account but for almost thrice the value of what it should be. This time I spoke to Thulisile and told me that she would investigate, of which took almost two weeks while every day I get a call from other car track staff phoning for an outstanding balance on my account. Yes I reversed all those debit orders which I did not agree to. Eventually I get feedback that MY ACCOUNT NUMBER was allocated to someone else’s profile FFS. I told Thulisile that they can double debit me for the outstanding amount for OCT. Come November everything is sorted correct debit (but no double debit) – correct account but on the last day of the month I get an SMS that states “as per agreement I would pay the outstanding balance by NOV 30th”. Anyway I did the EFT the Sunday 29th. I get a call 1 Dec again for “outstanding balance” of which I told them that I have made payment and email proof the same day to Carmen Samuels. The next day same story the “outstanding balance call”. I emailed Carmen to enquire if payment was received and she said that she would forward to relevant people to update my account. So come Thursday of the same week I get a call, but saying that they have received my payment and will allocate to my account. Friday I get a call asking for guess what? Outstanding balance!!!!!!!!!! Does your account people not communicate with each other? If this is the way a simple debit order update is handled what is going to happen if my car gets ****** and you need to find it???????
