Telkom Disaster

I am trying to cancel a Telkom service and have been informed that this must be done online. I cannot recall my password and any attempt for a new password takes so long to be received via email that the OTP has long since expired if and when it eventually has been received. I have sent an sms from my cellphone but response is that number is not linked to my Telkom account. Trying to call Telkom is frustrating and 2 mths later, I still have not managed to log my request to cancel this service. I was informed of an email address, which has not elicited any response after 3 such emails being sent. I no longer need this service since I have switched to Fibre with another service provider and am aware of many complaints such as mine.
