Home connect never informed me that I was signing a contract

They increased my monthly fees end of December from R388 to R488 which is R100 increase. They further increased again end of February from R488 to R588 which is another R100 in a space of 2 months. Now that I cannot afford their consistently increased service anymore I want to cancel the service, I'm being told that there is a cancellation fees. The system is now telling me that if I cancel before a 12moths I am going to be changed cancellation fees. I joined home connect in February 2022. Which is more than 12 months ago. I was never informed that I signed up for a contract but I was under the impression that i use what I pay for
