Underhandedly put on contract by agent

To whom it may concern. I have been a Cell C customer for over 20 years and in the past few years I have not upgraded my contract as I do not need a cellphone but just the minutes and data. To my surprise I was shocked to hear that I am on a 24-month contract since January 2024. Well to break that down, I received a call from Cell C agent in January informing me that the packages I and my daughter are on do not exist anymore and that I should change according to new data and minutes. I said not a problem as long as it stays in the same range and have similar costs. No where in this discussion was I informed that it will be a 24-month contact. The call was also short as I was called in the day during my work hours. I DID not request a 24-month contact and having it on a monthly bases suited me just fine. I did not realize that the agents use underlining tactics to slip contracts under your name. I would like this sorted and reverted to my monthly agreement. You are more than welcome to listen to the recordings and tell me where I agreed on a 24-month contract. To tell me to upgrade does not mean for 24 months!! I would like someone from head office to call me on this matter. Previously I was always assisted by Teboho's team and expect the same service! I called Cell C and was put through 3 people who were not very helpful. Sad customer service Cell C!! Was promised reference number but still waiting? Kind regards Franco
