Worst cell phone provider experience to date

In 2015, I moved over to Vodacom from Cell C as a result of bad service. I had no idea what I was getting myself into. Went to a Vodacom branch to do the move and asked to be on a UChoose Contract. The consultant confirmed this by informing me that it would cost extra per month to which I agreed. Needless to say, I was placed on the wrong contact: extra bills (data and airtime) run up for the past 6 months. A serious case of misrepresentation? Go to local branch to get copy of the contract (which I was never given) - \need to come back in 2 weeks - have to request from head office."In the meantime"
