Unable to Cancel Telkom LTE contract

So here goes:

Last week Wednesday I contacted Telkom to inquire about how to cancel my current contract with them. The person emailed me a link for the online thing with steps similar to this: https://www.telkom.co.za/today/media/downloads/Three_easy_ways_to_cancel_online_V2.1.pdf I completed this and after uploading my ID and hitting submit I got this: https://i.imgur.com/Q49U2O3.png

So I called them again and was advised to do the whole thing over again because, well...... they do not have a clue. They kept asking me what the error was. They were unable to understand my problem.

Tried it again on Friday, Sunday, 3 times today (Monday 17th) Spoke to 2 agents online directly from the website messenger thing this morning. Both of them kicked me off the chat, I guess if the questions you are asked are to hard to answer you just run away. GREAT SERVICE!

So I called them again couple hours ago. But all I get is "Do it online"

So at this point my patience is running very thin.

How the does one cancel this thing? Because if the call center cant help me who can?
