Bad Service Delivery

I have logged service queries month after month since March '21 with each service query being closed after 2 days. My WIFI has not been working since installation yet I am billed each month. After 9 calls to the technical team this morning of which all calls were cut and with only the 10th attempt I was told the cables were ****** (Since March 21). I would like to cancel my contract with NO PENALTY FEE as I am not the one who were in breach of service delivery within this contract. Many unhappy customers warned me to not take up any product with Telkom due to their lack in service delivery but I still gave Telkom the benefit of the doubt. I SHOULD HAVE LISTENED TO ALL THE MANY UNHAPPY CUSTOMERS!
