Incompetence, bad customer service and *****

I would like to lay a formal complaint about incorrect information provided to me by your trained consultant, I paid up my account last month and after that I spoke to your consultant Kagiso who promised me that nothing will continue being charged from my account as I have paid it up and she said she is making a note on my account. And to my surprise today I owe an amount close to R1200 for charges, who is fooling who here? I could have closed this damn account if I was told that I will be charged but instead she told me that because its paid up none of those charges will happen to my account. I want this matter to be fixed ASAP and close that credit account I do not want to do business with you ever again. I had extra money in my account and it looks like I got charged for using my own money how interesting for a financial institution.I called the bank 3times today got dropped twice and for the 3rd I get told that those charges are supposed to be charged, so much for customer service.
