CellC committing *****

I was contacted and notified about CellC increasing tariffs and whether I would like to upgrade my current phone, which I declined. I was then advised that I need to answer security questions and proceeded to do so. At the end of the call the agent asked me 'Do I agree to the conditions of the UPGRADE?' I told her that I am not upgrading as I changed my contract already in this year (1-04-2015) and do not intend to do so again. <br> After explaining to this rude and arrogant agent that I changed/migrated my contract on the 1st of April, she verified the information saying to me you are 'absolutely correct sir,' the asked if I agree the information provided is correct? I answered if nothing changes on my contract then yes I agree. I asked for a reference number but was not offered one instead I could call customer services. A short while later I received this Email:<br> subject : \ Contract Renewal Quotation"Dear Mr. Abrahams"
