Reap-off and false advertising

Upgrade without my knowledge! i was due for an upgrade in Oct 2018, i then received a call from Vodacom consultant on the 22/10/18 at 13:52:15 ref: 1- ********** 971285, who i told that i'm not upgrading because i'll be cancelling my contract in Jan 2019, she then offered me 2G of data as an additional promo, which i then explained to her that i'll be cancelling in Jan 2019, she said that would be a problem for me to cancel, i then accepted the 2G of data, to my surprise when i went to cancel in Jan i was told that my contract was upgraded and i can only cancel in 2020, i then called Vodacom who told that me that this can be reversed in Feb 2019 because whoever did this **** to me. In Feb i went to the deal to upgrade and i was told that i'm still not able to upgrade as this was still not reversed, i called Vodacom again on the 08th of Feb, who promised to reverse this from the 1st of March 2019, and i was given the following ref:1- ********** ********** . I am paying R187 monthly just for sim card as i do not even have a device let alone the 2G data that was supposed to be activated
