Cancelled service still being billed

My landline was cancelled a couple of months ago when they couldn’t resolve a problem with why the internet speed was so slow. This was after numerous complaints throughout having subscribed which I then resorted to canceling because it defiled the purpose of having WiFi at home

My internet from the very word go was always slow yet I had a 4mbps line , it felt like dial up I then about 3 months after reporting a fault opted to cancel because they couldn’t resolve the problem

Today I receive a text stating I owe R1039 for what? When I cancelled the line I wasn’t owing a cent but today I owe Telkom has a bunch of ******* that are ready to sponge off all the money they can from you until you run dry Service delivery? They don’t know what that even means let alone spell it

I’m sick of this and want you to NOW REMOVE MY NAME AND NUMBER FROM YOUR STUPID DATABASE!!!!! I’m done and I meant it!!!! Cancel the damn thing already and don’t bill me
