Bad service

I took a loan in 2016 and went under debt review, i have tried so many times to call Africanbank to resolve my issue with no luck, i have alot of statements that are not the same in terms of balances on other statements the balance is low on the other statements the balance is high, I have paid the amount that i owe the bank and their interest is now 50% that i paid and they always give me the different settlement amount, they always say they are busy investigating my issue until today I’m not getting a straight answer why they send me different balances on statements for example on the statements I requested in 2022 December and the month of December or any month the balance will be R47000 and the one I requested recently if i go to the month of December the balance is 25000, Mind you I already paid R99000 on a loan of R47000. I called Ombudsman with regard to this issue and one of members in internal resolution called me and i was told that they will give me feedback in writing and will call me after but i never called any call.
