Billed thousand times and money just goes down the drain

The way I am so fed up with vodacom if I had the energy I would take the to court for all my emotions wasted on this network.

To start with, when I activated my contract in 2016, whoever was assisting me was either on their first day at work or not properly trained because she opened 2 contracts under my name of which I was billed for until I noticed 3 months down the line.

A couple of months ago I called vodacom to find out about my settlement amount and I realised it was better for me to pay off the account upfront and enjoy the benefits until it expires because their costs are just over the roof.

I paid upfront and accordinf to the calculations done I was good to go until the contract ended and the person I spoke to in October advised me to phone vodacom on the 1st of November so that the contract won't go into the month to month as of December.

I did that and BOOM!!! a bomb hit me!! I am told that I still have 2 months to pay for the damn contract which I paid for upfront. Like where does vodacom think I get the money from? bad service, bad everything yet they just want to chow my money. I am so fed up with this network and their service and to top it all, the workers don't know anything about their jobs because they end up asking you questions you know zilch about.

I need a proper explanation as to where did the money I paid go to and how yal calculate this. I want the contract closed asap, I don't even want your prepaid option! I am fed-up with yal and your services.
