Rain 5G WiFi is a ****

I had the Rain 5G WiFi connected for use at my house. It's been one stressful ride, with little to no connectivity. The past two months have been particularly bad as I have not had any connection, despite paying the full amount. Worst part was my daughter had to go to a friend's house to complete her tertiary assignment because of the lack of connectivity at my hose. I tried several times to explain my frustration when calling their call centre. All those times they promised to resolve my issue to no avail. Anyway I then took a decision to cancel. I pressed the option "number 4" to cancel and held for an entire ten minutes. It's like the cancellation calls are not picked up. I then tried on the app - which does not have the cancellation option. I logged on the website and lo and behold! when I tried to click on the cancellation link, it does not work! Nothing happens. I clicked till I turned blue in the face. What a horror story that Rain is.
