Telkom a bunch of idiots

I have cancelled my landline a year ago, have emailed almost everybody at at Telkom, reported them at the Ombudsman and yet I am being charged every month.I have received notice that my line has been suspended and that they will report me to the credit bureau`s for not paying.I beg you to do that as i will sue you to hell and back! I have all the proof of your *********** service and incapability to do your work. How difficult can it be to cancel a subscription?
