Telkom atrocious customer service, almost 3 weeks later and no resolution in sight

I contacted the Telkom call on the 17/08/2017 regarding slow internet connection I have been experiencing since about four weeks before the call was made, the speed is so slow that we cannot stream movies or series or play online gaming, these are things we used to be able to do simultaneously . I explained the problem to the call center agent after which she asked me to reset the router and change settings, this was all done on previous occasions. She then asked me if I have an antenna installed which I do not. The reason why my antenna was never installed is because when we got the internet just over a year ago, we made arrangements with Telkom to have it installed. Me and my wife work Mondays to Fridays and most Saturdays so we arranged that there are people at our house to open for the Telkom technician coming to install the antenna. On the day the installation was to take place, 15 min after the time the technician was supposed to arrive, I was informed that the technician did not go out to work because he is sick. Surely they could have informed me the morning already that he would not be able to come, instead they informed me 15 min after he was supposed to arrive and I had wasted my family's time because they were already waiting for the technician. So I was told that they need to install the antenna and then test the signal and download speed, they referred it to their technical department and said that I would get a call to arrange for a time and date for the antenna installation. On the 18th I received a call from Telkom but could not answer at the time, I received an sms stating that the first attempt to reach me had failed and that is should contact the Telkom mobile team on 081180. I called them back about 20 minutes after they tried to phone me and once again had to go through the process of giving all my details and explain my problem from the beginning just to be told that I had to wait for the technical department to phone me again which should happen in about two days. I requested the number for the technical department so that I could call them and was told that I cannot call them, I must wait for their call. On the 21/08/2017 I received a call which rang for about two seconds and before I could answer it the call had ended, I received an sms saying that the 2nd attempt to reach me was unsuccessful. Luckily a couple of minutes late I received another call, the call center agent said that they want to arrange a date to come and check my settings, no mention of the antenna installation. The call center agent said that the call they received said that I was experiencing slow internet speeds and said nothing about an antenna installation. I told her that an antenna needed to be installed and then the signal and settings could be checked. An email was sent from TM-SOC to Home Support Outsourced and myself and Vanessa du Preez was cc'd in the mail and the mail requested to please install the antenna that was received with the package and had all my contact details on it. Later in that week I had not heard anything from anyone and decided to phone them once again, once again I had to give all my personal details and explain my problem from the start. I requested to speak to a manager and was put through to Darryl Sylvester. I explained the situation to Darryl and he said that he would get a technician to call me to arrange installation of the antenna. I told Darryl that they would have to come after hours or over the weekend as I cannot arrange that anyone open for them during the week. He said that he would check which technicians can work on Saturday and get back to me, to this day I have not heard from Darryl Sylvester. Yesterday I once again called the call center and once again had give them all my personal details and explain my problem from the beginning, I was simply told to wait for the technical team to contact me. I requested to talk to a manager and spoke to Sibongile Malinga, I explained everything to her and she said that she would find out what is going on and get back to me by 13h45, it is now a day later and I still have not heard a word. Based on how Telkom assisted me during the last three weeks, I will never use any of their products again
