Telkom Cancellation Struggle

I would just like to complain, like so many others, about the cancellation procedure where Telkom is not cancelling a service. I logged a call on 22 March, nothing happened, until I tried to follow up before 30 days have passed... They cannot help you if you have not waited for 30 days at least... So, then, on 24 April, they agree to escalate the issue - no response received yet, and I have already not been using the service for a month. Now... I wonder - I am not at the property as of next month, and i am not planning on paying for Telkom not being able to cancel their service. What can you do? I would like to speak to some Lawyer to find out what I can do to prevent Telkom from charging me - is this not against the consumer protection act? I have given ample notice, so they are in the wrong.
