Changing the price of the contract while the duration is not yet end. And not be informed by the sales agent that prices mite change during the duration of the contract

My name is Petrus Thabo Rahlao. I have a home WiFi contract with mtn. I took the contact because I was told I'm going to pay the subscription fee of R295 every month till the contract ends. Now I get sms that the the premium is going to increase from the first of February 2026 which I was not told from the beginning of the contract.

This is a mis-representation to the customers. I took it because of the price now suddenly the price increases. I'm not willing to pay new price. I'm willing to continue with the price I was given from the beginning of the contract
