Service Sucks

I'm honestly not sure who is worse between the Isp and the provider. I called Getwiza and raised I'm having intermittent internet issues everyday for a week. They told me from remote access, never coming to check themselves that is a complex problem with too many "wifi uses" in close proximity. Then my internet stopped completely. Now it's the ONT device that needs to be replaced by the fiber provider which could have been solved on a site visit to establish what the root cause is. Nevertheless, an appointment was booked, the time came, nobody arrives. No calls to say what is going on, where is the technician, no answer on phones. Nothing... Just all around bad service from both companies Getwiza and Fiber Geeks.
