Upgraded my account

On 15 Sep I received a call from Annalisa informing me that at the moment I pay R 230.00 per month for my 2Gig data contract. I have never paid that amount in a month. Where does she get her information from.<br> <br> I specifically asked her if I would still get the night time (night owl) data every month and she assured me that I would. My night owl data disappeared in 1 Oct. On 29 Sept I still had 1.8Gig data left to expire end Oct. On 1 Oct it was gone. At no stage did I ask for my contract to be changed to a Top Up contract. I wanted it to remain the same. What happened to my 1.8Gig data that I have already paid for. I did not use it. How can my data just be deleted.<br> <br> She OFFERED me 4 kinds of value added services which can only be activated when I receive the SMS's. I never activated it and I never gave authorisation for R 172.00 to be deducted from my bank account. How can you charge me if I never activated it. I want these subscriptions t0 be immediately removed from my account. <br> <br> I normally don't answer Private numbers at all. Heaven knows why I accepted this call. I do have the recording of the call on my phone should you require it.
