Bad service from Telkom

Telkom terminated my landline from their side towards the end of October 2020. I informed them, with scanned ID etc on 14 Dec. No reply. I completed an internet cancellation form on 24 January 2021, no acceptance notification again. I keep getting accumulating accounts though. At this stage I am highly irritated. I reported the matter to Hello Peter shortly after the termination, as the consultant was very rude.
