No fibre connection for a week no resolution or communication

Have been without fibre connection for over a week now, called the contact cebtre and the only resolution thay have is that they logged a call and person handling my case will call when they call. No feedback no nothing I keep having to call back to only be told the same thing. I work from home on severs and need a reliable connection please tell me if you are unable to help me so I can stop giving u my money and find a provider who can as this is now affecting my livelihood , will await your feedback
