Telkom query fiasco

Telkom charged me for a 200 GB soft cap on top of my unlimited package. They did not installed a 200 GB soft cap at my home. They installed a 10MB unlimited DSL line and promised me I will only pay R 806,01 per month. I ordered this on 17/10/2018 at 12:15. Can they please listen to the recording.

Despite of numerous calls, I end up with the same answer: they logged the query and will come back to me. There is no one else to talk to, to escalate the query. I have spent at least 2 hours on the phone with them but no luck. I am sick and tired to hear the same message everyday: we will come back to you. hahahaha
