Bad service from Telkom

Good day I have a contract with Telkom and it started mid August, I called their care line on 10213 and we had an agreement that they will deduct R269 on the last day of the month as the don't have the 28th as a deduction date on their systems. On September they deducted R483 which I thought it was from mid August to the whole of September which I didn't have a problem with. Well October I received a message that said I should pay R476 and I didn't understand why, I called their customer care line on 180 and was told that that amount included the rejection fee as they tried to debit on the 25 and I told them that I don't get paid and that the agreement was to deduct on the last day of the month, I was told that they're going to change the date and was given a reference number and was told I will get a call from their back office within 21 working days, well I waited until now noone has contacted me instead I am the one calling. November same thing happened and I was charged R943 on the 28 and R913 on the 30, I called on the 30 wanting to understand without no luck of a clear explanation and still received another reference number and was given a callback within 72 hours and until now noone has contacted me. I called again on the 04 still no explanation. I seriously need answers and my money back as am afraid if I reverse the money my name will be ruined.
