NON EXISTENT SERVICE - SUPERSONIC

We have experienced numerous issues with the fibre connection, more than several calls at our own expense and the issue is still not resolved. There is intermittent drop / lag in the fibre. It is honestly unacceptable, no-one takes responsibility to get to the root of the problem. The fibre is used for business, no fibre no income, who is going to be responsible for these costs and the wastage in phone calls every few minutes. In the beginning we had no issues, now it's like every second day. To try and get Management involved is a "no go area". Some technicians are absolutely clueless when it comes to how the fibre operates. I need to understand the cancellation costs and look for another service provider unless SUPERSONIC can dramatically improve their service TODAY.
