Vodacom Package Migration accepted on misleading cost provided

I have been trying from the 31st May 2022 to rectify a migration that I was convinced to make by a call centre operator on 20 May 2022, on the premise that my total monthly account which includes contract package payment, handset installment, as well as netflix subscription would remain unchanged. At the end of May 2022 I discovered that the total amount I was going to be paying for my next bill was almost twice as much, since the new contract package price alone was approximately the same amount as the total amount I was paying (previous contract package payment, handset installment, as well as netflix subscription). I then decided to reverse the migration on the 3rd June 2022 and this was confirmed as being resolved on the 4th June 2022. I then receive my invoice and statement for June 2022 and I am still being billed for the new contract package and my bill total almost twice as much as my previous monthly vodacom bills. At this point I want the contract migration to be reversed together with the costs, that I did not agree to. I have been calling the customer care number almost every day and this issue is not getting resolved. The call either gets cut, their systems are offline, I get passed from one department to the other. It would be nice to deal with a single contact person who can be held accountable and be contactable for feedback regarding this issue.
