I was deceived and I seek justice!!!

3 weeks ago a Vodacom agent contacted me regarding my current contract. A white guy, male, could hear from his voice. He said to me that I'm currently paying too much for so little data and minutes, he further more said that we can change that by converting to airtime instead of data and minutes and I'll be able to buy data and minutes with the airtime. I asked if this will be an added cost to my bill and he blatantly said NO, I'll still be paying the same installment I'm currently paying, so I agreed. Hawu, a week later I log in to my Vodapay app, and I notice an extra cost has been added to my monthly bill. I contacted Vodacom immediately with eagerness to find out what's going on, and I did. Guess what??? That agent did not convert my contract, he actually upgraded it without my consent just so he could fill up his pockets. This is a felony and I will pursue a ******** case against, I even told them at Vodacom that I want to open a ******** case, can they help me, the agent laughed ... So now, I'm going to seek help from the Consumer Ombudsman. This kind of ******ion needs to stop!!! Deceiving an individual for personal gain is a punishable offense and I shall see it come to pass🤞🏿HOW MANY ARE WE???
