Service virtually non existent

I requested my fibre to be moved 3 weeks ago. They told me someone would call the same day and no one called. When I called a week later they told me nothing was logged and I needed to do the process again. I was told I need to wait 1 to 2 weeks and it is over 2 weeks now. No one is answering their phone and they are not answering my emails. I am not able to work and I am losing business.
