Worse Service

I took out a R299 data line in August 2020, I specifically went into the Lephalale Vodacom store and ask one of the sales person that I want a data contract. She showed me the ones that are on special - they were not in the pamphlet. I chose the R299 one, 30gb of day data and 30gb of night data. Came month end the bill is close to R700. I initially thought its the kids line and didn't check. 1st of March I decided to cancel the kids line, the last debit was supposed to go off on the 25th of March. End of April the bill is still the same, called the cancelation line to be told the contracts were not cancelled, requested the consultant to check the billing info, only to find out that the data line that was taken in August was an open line. She advised me to go to the store because this info was never shared with me in the store. Went to the store yesterday and the person who was helping me told me I have only 1 option, downgrade to 2gb because the person who initially assisted me with the contract is not there to take "accountability" and bona there's nothing they can do on their side,and it's my responsibility to ask if the line is open or not. To say that I'm disappointed is an understatement, Vodacom is basically ripping me off, currently I'm paying around R600 for a contract that I was supposed to be paying R299.
