Worst service ever

The service we received from supersonic was terribly poor. After taking a month to activate our subscription. The router only arrived at our premises 7 days later. Their website states that you can use your own router. We phoned them to assist us to setup our router and they advised us that this is not possible. You literally wait an hour for them to answer your call via their call center. They then advise you that they need to transfer you and drop the call. After numerous attempts to get assistance from them to activate their router which is not working and should be "preconfigured" according to them. We still don't have any fibre.
