ABSA Vehicle finance account issue.

Good day, I have on a daily basis received a call from ABSA vehicle finance informing me that i have an outstanding/missed payment on my vehicle which was settled in September 2019. I have also received my log book from ABSA and transferred the vehicle to my name. If there was an outstanding amount due to ABSA why would ABSA provide me transfer documents and log book so that i can register the vehicle to my name. This account was also linked to a debit order, what went wrong on absa's side. What seems to concern me is that absa is now trying to exploit it client by calling me daily requesting a payment which make no sense a year later even after a note has been placed on their system stating that their admin office needs to correct their system. Their staff never checks these notes prior to calling. firstly that seems to be wasteful expenditure from their side. Secondly seems like due to the covid pandemic they are now looking to make a quick buck from their client to increase their revenue. Really sad to experience the above from ABSA. One of the reasons why I am in the process of closing my accounts with ABSA.
