What is going on at ABSA Home Loans (Debit order department)?

ABSA assured us that our home loan debit order was moved from our Standard Bank account to our FNB account. Last month it incorrectly came off the wrong account. When I contacted ABSA, they said they needed more documentation in order to do it (They never said this before that point, and in fact confirmed that all was in order). We sent them the required documentation and we were given confirmation that it was received (10th Feb 2022) and that all was in order. My debit orders came off now and once again it has come off the incorrect bank account. This was supposed to be sorted in December already. We are in March and I am still battling for ABSA to move a debit order. Twice now we have received confirmation that all is in order, when it is not. Can someone who is able to do something, please see what is happening and sort it out? I would assume it is not a difficult task to move a debit order? Each time there has been 4 people from ABSA included in all correspondence (I won't mention names this time, unless it happens again). But nobody seems to be able to get this right? Please sort this out and send me confirmation as soon as possible. If it happens again, I'll rather look into moving the home loan to Standard Bank. Thank you.
