Vodacom is a bunch of *******!

I am seriously fed up with vodacom!! I got a call from them saying that I am paying for things on my contract that i'm not using, and that they aren't SELLING me anything nor UPGRADING ME which she repeated more than 10 times, and that I am paying for things on my contract that i'm not using.. then telling me that i'm paying a lot and they want to assist me with lesing my payment. JUST TO RECEIVE A STATEMENT THAT MY ACCOUNT HAS BEEN UPGRADED AND INCREASED WITH R700,00!!!! FOR DATA THAT I DONT WANT!!! This is not the first time that i have had issues with this company and why I never answer calls in the first place!! Are there ******* working at Vodacom?? I want this rectified and will not be paying them until this matter is resolved. Before I received this call I got another call from a different person about the same thing and I clearly stated that I dont want to change anything to my account even if they were trying to less my account and had to cancel the call because she kept harrasing me to change it. I have called vodacom and the customer service agent had stated that i was indeed UPGRADED??? I requested credit and for my account to go back to what it was. If this is not going to be sorted, I am taking it further!!! I am DONE with Vodacom!! I am not paying for this as it's NOT what I agreed to!
