No assistance for cancellation

I have been trying for three days to have A BUSINESS LINE cancelled ********** 195 I have followed the prompt for online and it gives me an error that "cannot associate this service, please contact call center" I contacted the call centre 10217 who WOULD NOT HELP, just gave me an email address ********** while she chewed food in my ear That address came undelivered. I called 10217 AGAIN and was given another email address ********** It then came back with undelivered error I called A THIRD TIME to 1027 and was given a THIRD email address ********** which gave delivery failed. I contacted the chat service on the website - but its only for residential. Telkom will gladly take the money for this line that we NO LONGER want but we cannot even START the process of cancelling.
