The worst ISP I've ever had to deal with

The worst ISP I've ever had to deal with! I got in touch with them a month before moving into my new house, the fibre was only installed 3 months later. I now, again, have to deal with their terrible customer service. I have had 'internet without connection' since Saturday, I logged a ticket and have a reference number but no one has contacted me since and it's now Wednesday. I work from home and need an internet connection to do my job! Every time I call them, they put me through to CS and when I finally get through to someone they say I need to speak to Tech. Wasting my airtime, data and time! I would not recommend them to anyone! In the wake of COVID with most of their customers working from home, it is important to sort these issues out with haste and speed! PS. My neighbour has exactly the same problem as me. Unfortunately, I have to deal with them as they are the only ISP in my complex.
