Vodacom penalise users because of their OWN errors AND MISTAKES

My experience with Vodacoms Account department has been the absolute worst. I have been struggling for months to solve this issue but i get a run around everytime, Im tired and honestly lost hope in anyone that work in the accounts department because it looks like no one knows anything, i have never in my 6+ years of working in Customer service seen service so pathetic. Vodacom might aswell just close that department because they are of no use. I am being charged an extra R100 every month on my bill because of the accounts departments error, they never deduct my account then still penalize me for it🤣, i pay the refused to pay it because it wasn't my fault and they said they would remove it next month i now owe R200 because they added another R100 because i failed to make their late fees payments which again was their fault 🤣, i got sick and tired of this and just paid my installment and the "penalty fees of R200 onetime on the 4th of October, ohh wooow how im not surprised, that they added another R100 to my bill this month even though the debit order has been off for two months already ahh ya Vodacom Accounts department? You guys are literally wasting the companies money🤣
