Pathetic service from Telkom, or lack thereof!!!!!!!!

I had a contract in 2014 which was cancelled after contract expired. In 2019 Telkom decided to start debiting me again for the same contract that was cancelled two years before. I cancelled it again on the 17th of April 2019. No December 2020 they blacklisted me for the same contract, I have proof of cancelation and the call recording. Can Telkom please cancel this contract for the last time and remove my name from ITC, this is ridiculous!!!!! I am so frustrated with the lack of service from Telkom. Please phone me and stop threatening me!!!!
