Raised bill, wrong contact given

Cell C direct's Ada Van Wyk offered me a contract with the company. I accepted, i was offered two cellphones to choose from, which i settled on the Samsung J1 for R120/R130 a month. I specifically told her i wanted a contract whereby i can put my own airtime, afterwards i said a top up contract. I waited some time before the cellphone came and during my wait i continually emphasised my specifications and that it must be a top up contract. Now, January 2016, my bill came to R385.68. When i queried this i was told i was either not on a top up contract or that the contract limits weren't explained. I am not going to pay for someone else's stupidity, yes everyone wants sales but not like this. I am terribly disappointed with cell c's consultant. If you want proof that i requested a top up contract it will be on voice record and your consultants email. This needs to be resolved before month end by when my debit goes out or else i will take this further as i am not the one at fault.
