Telkom Dismal Service

I upgraded my fibre connection from 20mbps to 100mbps roughly 2 months ago, since then i have been billed twice for this service however still receiving the slower line speed, after hours and hours speaking to call centre assistants i am still no further than i was a month ago when i first logged a call with my problem.

This company has no idea what is going on within their own departments and no way of sorting out a very simple issue. I am going to stop payments to Telkom all together as they cannot deliver services or rectify problems.
