Trying to cancel and hearing crickets

I am emigrating and have sold the property. I want to give Telkom a months notice to cancel the line as that is what is needed I believe ( through google only because no one answers me from Telkom itself)<br> <br> Had great service hwen I opened the account but now I call the centre and I get hung up on before speaking, the live agent chat service simply tells you an agent will be with you shortly, 2 hours later and I am still online wiht no response ?<br> <br> Just want to cancel a simple fixed line otherwise you can try to find me when I have emigrated and stopped paying.
