Fibre contract of 100mb delivers <20 and charged full price..

After multiple calls on Monda and speaking to call agents who cannot escalate calls to managers or transfer you(working from home and in one case agent was in the bathroom) I was able to leave a message for a manager to phone urgently) I did receive a call from a gentleman who said he was a senior client services leader and asked what the problem was. Explained and said it's going on 4 months and service was shocking and he acknowledged and asked me to be the Telkom engineer again (Have done this more than 20 times with sane result) This time however he said i had changed configuration etc...bu not having the Telkom password I could not have done this. This means Telkom staff can change your settings whenever they wan and no log is avsilable(scary thought) After an hour of being their engineer he promised he would investigate and phone me back today. Once again NO call back, broken promises and a fibre line that operates below 10% of what it's supposed to and i the paying client am still no where near getting the service issues resolved and financial reimbur*****t for the past 4 months. (Getting a Telkom staffs name besides being difficult is of no use or consequences because trying to get them again or reporting them does not work as there is no CRM system that logs your calls, records issues and actions who and when you spoke to them. Telkom you are an embarrassment to the Technical industry and would not exist in a free market. THIS ISSUE NEEDS TO BE RESOLVED URGENTLY and get your engineer to sort this out. I am not your engineer on the ground and I don't have time to follow a script that you have and waste my time sorting out your problems instead of doing my own work
The time I have spent sorting out this problem should be charged back to you at my professional rate per hour.
