Harassed by Telkom

I'm being Harassed and bul**** by Telkom. I took Fibre ( WIFI) with Telkom at the beginning of 2024, everything was going well up until I notified Telkom that July 2024 I am moving out where I use to stay and I would like to cancel my contract with them. Whenever I try to reach Telkom on the phone their cancellation department system was always down I tried more than four times to call them but always the system is down. Three months down the line from July I tried to acquire credit from another institution my application was declined and when I try to check on clear score my credit score was negatively impacted by the behaviour of Telkom not cancelling my contract. I called them around September to ask the amount of money that I owe, they highlighted that I owe R980 for Three months ( July- September). I paid that amount even though I was no longer using the WIFI and moved to a new place. December 2024 I received a call from Telkom threatening that my account will be handed over to attorneys if I don't pay for the Months of October and November 2024 at that time I just said '' it's fine we will meet in court'' but today to my surprise they sent me a statement, on the statement I'm owing them Money for three months even though During the month November I finally managed to talk to one of their agents and cancel the contract. To my surprise even now my email address which in registered on the system is blocked I don't know why. What is new as well this year 2025 there's no option where you can talk to an agent. Assist me please, I'm harassed and ambushed by Telkom.
