ABSA Vehicle Finance Incompetence

I requested ABSA Vehicle & Asset Finance to change debit orders for my 2 vehicles with them on the 3rd of February 2022 as I had changed banks. One vehicle and the other has not been changed up to today. Refilwe Mokoena helped with me regard to my request and she confirmed the changes. Last month i was advised by their collections dept that my vehicle is in arrears and I contacted their customer services dept & spoke to Byron Jansen on 22 April who assured me that my account was not in arrears. Few days later the account was confirmed to be in arrears and i had to make a payment which I made few days later and requested that my credit record must not be impacted negatively about this. After I had made the payment I sent Refilwe the proof of payment and requested her to sort out the credit bureau information. She never bothered to reply to my emails. I have realised that the debit order has not gone through again this month after receiving confirmation from Refilwe on the 22nd April that account banking details were updated. This is rather embarrassing from ABSA and I need this to be attended to urgently.
