Worst internet provider EVER!!!!

I have literally never experienced as bad internet provider as Ihappyfifibre!!! I have been so frustrated with this service, especially because there is NO service at all!!! From the start, I have been struggling with them. My internet doesn’t work for days at a time, and if you ask for support (if your lucky, they might answer),no one knows what’s going on! The just switch off my depit order without informing me and shuts down my internet due to outstanding amounts. They are very quick to respond if there is an outstanding payment (which is not even your own doing) but when you actually needs there help, they don’t reply emails or answer calls. It feels as if I am running into a wall over and over again!!!!!!! How can one business be so bad???!!!!
