Third Time Internet Has Crashed in a Month - Useless Service

This is the 3rd time in a MONTH that Metro Fibre has crashed, leaving my mother without wifi for days on end as they take DAYS to send out a technician to see to the problem, and never work on weekends or public holidays. Why does my mother's internet keep crashing with your fibre, and why do you never make your customers a priority?

I signed up to Rocketnet to provide my mother with uncapped fibre as she is a social worker and in urgent need of access to the internet. They connected her to Metro Fibre and it's been nightmare after nightmare with them, year after year. We have no other fibre option so are trapped. They never offer an apology for their outages, and never escalate the issue. They clearly don't care about their clients or their circumstances. The biggest waste of money - please DO NOT go with them if you don't want constant headaches and poor, poor service. We are at our witts' end. We want a solution to this poor excuse for a service provider.
