I have been sending requests to get my contract canceled but no one wants to assist. I keep being told that I should log on to the Telkom website, but when I do it shows that I do not have any accounts to display. They keep charging me a R100 subscription

I have been sending requests to get my contract canceled but no one wants to assist. I keep being told that I should log on to the Telkom website, but when I do it shows that I do not have any accounts to display. They keep charging me a R100 subscription fee even though my contract ended in February. I asked them to cancel it but they didn't. The service from their chat agents is totally useless and they don't send sms's like they say they will or show effort in assisting you. I need this stupid contract canceled, and I'll definitely not be referring anyone to open contracts with this company. I swear.
