Vodacom is bad

The problem started in August 2023 when I called to vodacom cancelling dept and instructed them to cancell 2 of my contracts but instead of cancelling the contracts the consultant upgraded all of the contracts I had with vodacom. I called them the following day on the 02 of August to have that upgrade reversed and so they did but than the problem started when they billed me for that upgrade of which I refuse to pay and again on the 1st of September 2023 I again called their cancellation department to have that same contracts cancelled but the very same thing happened they upgraded all my contracts again although I had informed them to only cancel the 2 contracts and I again they were holding me responsible for the bill. I lodge numerous quiries and they could not resolve or would not resolve it because they were money oriented instead of customer service. They when as far as to put negative information on my credit report. I did registered my complaint to the Customer Consumer Committee which look into the matter but till today have jot received any feedback. I want them to remove that negative instruction from my credit report and sensitise their consultants to do what the customer wants and not do what they see fit just to get commission in their pockets.
