Terrible customer service from Nedbank Home Loans

Having a Home loan with Nedbank and i was behind with the monthly re-payment. I made arrangements to pay the arrears and until i paid them in full. My account was up to date since July 2019 and i never missed any instalment since then. To my surprised when i look at my credit report in July 2020 i see that i am in arrears (one month) in my report and i thought it is just one of those errors but it was nothing like that. I the received a call from the consultant who wanted me to make an arrangement and i said why should i make an arrangements of something that i know nothing of and demanded to speak to the manager. I requested to speak to the manager for over a year and NO one except the Team leaders (3 different) who kept me hanging until today. I left numerous messages, emails and NO one came back to me. I was assured by one of the consultant (name withheld) that if i can pay around R700 my account will be up to date and i did. Nedbank service is terrible and the home loan teams are so arrogant and do not even bother return your calls so that we can resolve the matter. The matter has been dragging for over a year and i referred them phone recording to substantiate my claims and they confirmed that is true. i have proof of emails sent and nothing. It is so disappointing that they can just destroy your life and NOT bother to assist.
