Metrofiber pathetic service

Metrofiber entered my complex uninvited and did random maintenance checks, I presume. They disconnected my wifii without informing me. When I called them to query, they asked me to log a ticket with my service provider MWEB. However, they didn't request a ticket number when they disconnected the line. At the time of abrupt disconnection, I was on an international business training session whereby I was the host. Unapologetically, they now tell me that it takes 4-5 business working days to attend to this matter. Technicians are not available on weekends. Pathetic service from Metrofiber and Mweb (unable to expedite a prompt turnaround).
