Cancellation nightmare!

I have been trying to cancel my Telkom line for the past couple of months now. I used to use Mweb as ISP via Telkom. When I switched to LTE, I cancelled the Mweb and wanted to do the same with the Telkom line. Unfortunately their level of uselessness surpasses even my worst expectations. Such incompetence should not be permitted in any business. It is astounding that a task as simple as cancelling a service could prove so impossible. It is sad that a once proud company have such pathetic customer service. I would lower my head in shame were it me and my company.
