Read this before considering Supersonic Fibre

We ordered Fibre through Supersonic and the experience started fine. We were contacted to install the fibre line to our home within a few days. The installation went well apart from finding out that the line at the box on the street was damaged. They contacted another team and they fixed it the next day. Without knowing what the next step was, I contacted Supersonic and explained they installed the fibre in our home, and apparently that was the right thing to do because they only then started the activation process. I waited for the line to be activated and all lights on the Huawei box to stay solid green. After this I tried to connect my own router to this box and connect to the internet to no avail. After spending hours on the phone (mostly waiting to speak to someone) I concluded that my router simply does not work. I waited for the router that they couriered to me as this would surely work. The router arrived and also did not connect to the internet. It has now been 4 days, phoning them every day, going through countless "s****ed" technicians, doing the same stock standard diagnostic routine (reset routers, login to router, setup manually) and asking to be put in contact with a manager. Nothing. No one phones me back and apparently all managers are on conference calls and not available when I phone. Best of all, after they contacted Huawei to see if the problem is with them, they never got back to me, and when I phoned back they said they don't know what the problem is or what to do to resolve this. Hands in the air. As a customer I expect them to be proactive - what am I supposed to do about it you are the service provider. I asked to be migrated to IPComms (I wish I knew I could use another ISP before going with Supersonic) but I have to wait 30 days and will probably not have internet during this time. Supersonic was voted top ISP 2019 by MyBroadband and I chose them based on this. I honestly don't understand how they got this award. I phoned IPComms on a public holiday and took a chance and selected to speak to a technician. This guy was extremely knowledgeable, very competent, and I only waited 2min to be connected to someone (compared to 45min with Supersonic). I am not a paying customer with IPComms yet but this guy didn't hesitate to answer all of my questions. I was impressed. Will be doing everything in my power to migrate to IPComms ASAP.
