IMPOSSIBLE to get Telkom to respond to a cancellation request

I am finding it impossible to cancel my Telkom landline and ASDL account. I have emailed: ***; ***; ***. In addition I have sent a registered letter to Telkom’s registered office – from what I can see from the tracking it has not yet been collected and that was a good few weeks ago too, when the notification was placed into the Telkom bag. I have also phoned 10213 – After pushing buttons 1 and 5 a voice recording tells me to close the account online but that is exactly where the problem is. I cannot get their online portal to let me get past step 2 at most. I tried and also got an IT specialist to help me too. He got no further than I. It would be easier to try to engage with an extra-terrestrial on Mars than this constant attempting to get a response out of Telkom. Hoping this now elicits a response.
