Vodacom increases my contract installment without my knowledge and consent

I am utterly disappointed in the service and the manner in which Vodacom is managing my account. I have escalated to the CEO office with regards to a handset that was being deducted from my accounts with regards to contracts that have already expired. I received an email that it has been resolved and no further reductions will go from my account. They reimbursed my Vodacom account for the previous months where they incorrectly debited my account. This month I was debited for that same device again and was informed by their accounts department that they have not received any form of communication from their CEO and therefore i am still paying for a device I no longer have or make use of. My other three contracts has also been increased without my consent. I have contacted Vodacoms accounts department as well as their CEO and still have not received feedback. Vodacom currently is putting a massive strain on my finances. Their agents are *********** , don't know their job and every day i get contacted for migration which according to them its not suppose to have an impact on your monthly payment, but it does and I did not agree to any extra charges on my account. i want to be compensated for my time and all the incorrect amounts being debited from my account and the financial strain they put on me. I want my accounts to be resolved ASAP as I have not gotten any form of feedback or communication from their side. Notes are not being made when I call in to lay down a complaint and therefore each and every time i need to reexplain to different people . The agents are not skilled and do not understand the queries that are being logged. I want to be debited to my personal account .
