Trying to cancel my account

I have tried canceling my account now for the last 4 months and had no luck. I phoned in to cancel my account as I do not work for such a lot of money anymore and can not afford it. I was then told I can not cancel the account but Isabella Garcia will make it less, where I rep**** no I want to make cancel it. They agreed and then R 400 taken from my account for my product which I cancelled. Then this month R900. I need to cancel this account urgently as this is stopping me from even being able to buy food for myself. I need answers urgently and my account cancelled. If there is more money taken off of my account from Isabella Garcia I will take this further as I have even messaged and emailed you now. This is negligence from your customer care department.
