Internet issues for nearly a month now - Enough is enough

This time, I am done with Vox Telecom. My problems started after/during an upgrade on your side. I logged an issue, no customer service, and you closed the ticket days after, due to an apparent issue in the Camps bay area, while I am staying in Melkbosstrand. The issue is still the same. I tried your "Voxy"services, as I was not prepared to hang on a phone for hours again and what a surprise. The technician on the other side clearly either did not know what to check for, or really did not care. I had to remind him numerous times that I am still online waiting for him. After 3 hours, hoping to get something positive out of the ordeal, I really could not stand it anymore. The response I received from the technician at the last moment was "Apologies, I had technical difficulties on my side" and immediately after that dear "Voxy" closed the ticket as resolved. I can only access my applications/games via Vox Telecom internet services from 5 o'clock in the morning until early mid morning and only when nobody else are actually connected. In the evenings it is just impossible and I must use my cell phone data and create a hotspot on my cell phone to access my applications and play games. In other words, I pay you for No Service and I have to buy data from my cell phone provider in order to access what I pay you for. And please do not tell me the issue is because of the undersea fiber lines that were damaged last week. My issue started in the last week of February already. I am not going through all the trouble like last year again. I am not going to let you tell me again that nothing is wrong on your side. If nothing is wrong on your side, escalate the problems to resolve your customers' issues. It is not a favour you do for your customers. That is your duty as a Service provider and that is what we pay you for. I will rather cut my ties with you and close my account.
