No internet connectivity

I signed up for supersonic Fibre over a month ago, and I was scheduled to move over from my previous isp on the last day of the month. I have been sitting without connection the whole day and unable to work due to this. I have spoken to numerous people and calls today with no assistance or feedback from supersonic. I have been promised calls and activation so I don't face any issues with my work but this was all a lie. It seems that they have no customer service for there clients and are not willing to help. If I only knew this would be the issue I would have not moved over and would have stayed with my current ISP. It seems that they promise call backs just to get you of the phone and don't return with a solution.
