The worst ISP I’ve had in almost 20 years

I changed my ISP to Supersonic per 1 March. They delivered an LTE router very quickly, and I was hopeful that they really were the best ISP in SA at the moment. Fibre was to be activated at the beginning of March, as soon as my previous ISP released the line. A techie came about a month ago and delivered the fibre router, but couldn’t get it going because the line hadn’t been activated, which was supposed to take another 24 hours. Since then I’ve been given the runaround. The WhatsApp support is absolutely use, the techies say it’s customer support or Vumatel, depending on who you speak to. Customer support says it’s not them, it’s the project group or my previous ISP depending on who you speak to. All of them tell it’s been escalated but nothing happens. I’ve had internet for almost 20 years now, and Supersonic is the worst ISP I’ve come across.
