un professional services from NEDBANK Homeloan Collection Department

I am disappointed with the unprofessional service I got from Nedbank Home Loan Collection Department I made contact with Nedbank collection department over an authorised homeloan de*****eck they had done on my standard bank account on the 13 May 2024 that resulted to resulted to a penality fee . i spoke to them and they kept referring me to pillar and post unable to sort out my problem OR give me a solution to the issue they have created on my standard bank account. My account with them is up to date and i was wondering why would they do this .
