ABSA - Incompetency

Since September last year, i had paid up a loan with ABSA. They continue to take money off my account for this. I have now called them for the 4th time to reverse the payment and resend the closer of the loan account. What infuriates me is that they do NOT re-imburse all the bank charges, they do not reimburse the countless hours i have spent trying to get through to the call centre because they are working "COVID Hours". So at the end of the day i am loosing money because ABSA do not know how to update their systems. How do i go about getting ABSA to reimburse for the hours spent on the phone, i get paid per hour and each hour i spend, i loose an income so this just accumulates to what they should rightfully pay me back including the banking charges and cellphone calls. I find that this is completely unacceptable and they ignore the questions when i ask about the above. They do reverse the debit of the loan and resend the paperwork but the other queries fall on deaf ears and they simply offer nothing.
