Settlement is not a settlement with Nedbank

On June 6 I called in to get a settlement amount on my personal loan, they sent me a settlement quote letter and I paid the exact amount quoted.

Then in July Nedbank debited my account with R426.08. When I called in to find out why the lady told me I was quoted a wrong settlement amount which means my account was still active with fees and other nonsense they charge. Now who's fault is it if they quoted me the wrong amount? A settlement should be a settlement.

This is all a **** to charge people more money *********ly. Shameful.

FYI, I won't be getting my car with MFC anymore.
