Misleading sales

I was called about 3 weeks ago by one of vodacoms agents advising that they are assisting me with a migration to a better plan of which I advised the agent if it's more then what I am currently paying that I do not want it she then advised me that it will be less , a few days later i received a statement showing that i will be paying 400 rand extra and I then called Vodacom of which they logged a ticket told me to wait 3 to 5 days no one ever got back to me today i received a statement again showing the same ridiculous amount i called Vodacom and was then advised that the refund and change back to my previous premium was captured due to me being mislead and then at the end of December my debit order will be the same as i was paying i then asked what is going to happen with November debit order i was told by the agent they not sure they will have to log a new ticket or i will have to speak to the accounts department i told the lady that i have been trying to get hold of the accounts department but it keeps telling me that my account is not in arrears and Tobi will Sms me I don't want a SMS from Tobi I need someone to call me urgently I need someone that is going to help me sort out this mess without having to transfer me to a different department while transferring then the call cuts and no one from Vodacom calls me back.. quick to call me and sell me misleading **** but slow to fix the mess.. I am tired of phoning after Vodacom, I need someone to take accountability and fix it I have been a customer of vodacom for many many years and I have never been this upset.
