No service, poor provider

I have called, requested call backs sent them messages on Facebook. Still no resolution and no one willing to assist with my queries. My account is billed incorrectly. My fiber goes off for days and I am unable to change my password and manage my usage. Still no assistance. Highly frustrating. You cannot review them on Facebook or any social media platform due to their settings and the only people who answers calls are the sales team... I have screenshots of every time someone promised they would get back to me... What a joke.
