African Bank lists arrears whilst Garnisheed

I had a loan through furniture city in 2011. I was garnisheed in 2013. The garnisheed amount has been paid through monthly from March 2013. Imagine my surprise then to be informed that I am listed as having arrears amount with African bank even though they are deducting from my salary monthly. What kind of shady practice is this? I have contacted the attorneys who completed the emoluments order which on its own looks highly suspect and they have not gotten back to me. Added to that my arrears amount reflecting on the credit bureaus is excessively higher than the capital amount which is what is collectible. Next stop banking ombudsman.
