Still Charged, but Balanced paid...

So why do we get statements, to settle our account or pay installment due. So now the issue is that my father has settle his account by paying the full amount reflected on his Game Statement. He has received a new statement the following month reflecting a new balance owed as R5.01, which does not make any sense. If you settle an account which means there should be nothing outstanding and the organization (RCS) should not be charging you for services or any other charges when you have a zero balance.<br> So my question is why are you taking advantage and harassing a customer that pays there account on time. <br> <br> Please correct this issue, as I will be posting on social media if this does not get resolved. <br> <br> Thank You,<br> <br> Zayd Pretorius on Behalf of Father (Michael Pretorius)
