Vehicle Finance over-charging

I'm extremely not happy with how Absa VF has handled my wuesry whole week I'm waiting for solution. We settled my account on 22 January, what is weird, in all this all your still did not assist in closing my account after numerous calls and a debit order went off after the settlement, the lady I called and requested she closes it ***8 reference number. The other request I made ***1 - 27/01/2022, did not do anything wrote her own thing on the notes. Was not very helpful at all. I am taking, I'm giving Absa a day to resolve this or I take it up with ombudsman. Whole week I'm calling and none of its staff actually does anything. That time 3900 left my account
