High interest fees company cannot explain and poor customer service!!

The worst customer service ever. I received a call regarding my payment arrangement which was the 4th time in just 2 hours. All the consultants that called me gave me different balance to my account which when I checked my statement all the amounts were different as well. One of the consultants told me that I will accumulate R300 interest for the month when asked to explain he couldn't I then asked to speak to a manager by the name of Ziyanda who gave me so much attitude even raised her voice at me. I went through the statement which the company sent me to no surprise she said she does not have my statement and asked me to send it to her. I was honestly willing to settle my account but due to these outrageous fees that the company its self cannot explain I will not.
