Been charged every month for a damaged line

My fixed line got damaged in August 2019, I reported it and the technician was assigned. The technician informed me that the cable was damaged and could and would not be fixed. I called in to inform the agent that a technician came and said that the line is not going to be fixed and told to stop charging me aand I was informed that I will be given an amount of up until the time the line stopped working. I paid. But Telkom is still charging me even today for a line that stopped working last year.
