Terrible service provider!

My fibre’s been off for a week now. Logged a call on Greenzone on the 18th (was off for 3 days at the time), logged in to see the status of the call- just to find that they closed it, they didnt follow up / phone me to see if it was working as yet or to trouble shoot. Been trying to reach them on their support contact number to no avail... not sure what else to do now. Paying for a service that I am unable to use.
