I'm not happy with the service for fiberstream

The experience I'm having with fiberstream is horrible they're service is poor I've been having problems with them for months now our account get disconnected every time at the end of the month, but the problem is we pay our account before the end of the month always that means the account doesn't do there job. And when you call they will take their time to help you. You will be on the call almost an hour. They will promise you that they will fix the problem but believe me it will happen again at the end of the month. You will call them in the morning and keep calling them till after noon still the wifi will be back at night and I think they doing that intentionally some times the kids can't do school work. Imagine you pay them and still buy data for the kids. And every time they will send you invoice that you haven't pay even if you did pay.
