Fibre issues and no show an bookings made

We have been with Supersonic for the last few months in our new house without any real issues, last week (week of the 14th), Supersonic technicians did something to the fibre steetbox, not sure if this was to install a new line for another house of fix different issue, however since then, as they drove away our line stopped working. I have been speaking to call centre agents for more than a week now about technical appointments.

Sunday (20/09), a technician from scheduling phoned me to arrange a time, and I have been promised a technician on Monday, Tuesday, Wednesday (Wednesday was even very specific - 15:00) and today Friday. Still no internet and with a call centre that can't provide me with any more information than... Please let me phone you back I will follow up.
