Telkom subscribed me for a deal I am not aware of ,they did it without my consent

I am really irritated with these stupid consultants from telkom excuse my being rude ,my contract was due to end on the 30th of June 2021 and I made it clear I am nolonger interested in any of the products they offered me . They subscribed me on a deal I never took without my knowledge. I think its time I took them to court because they do not listen they do as they please without the consent of the client.
