Incorrect billing

Their billing system has issues , I'm experiencing this for the second time now. My current statement states that the amount due for March 2021 is R1862.62 which doesn't make any sense, when I contacted customer care I was provided with a different amount(again). This makes ya'll very *********** and it also means that you are providing false information to your clients which is a violation of FSCA since ya'll are an "authorized FSP". Please resolve this and stop inconveniencing me, for I will escalate this further.
