Unable to get Fibre installed

I have been trying since October to have Fibre installed at my property. After numerous attempts and various routers I still don't have connectivity at my property. I eventually cancelled and have now tried a brand new installation and brand new router. I still don't have connectivity. I am told to wait 24 hours each time but the line was activated a week ago. In the meantime I'm being billed for a line that does not have connectivity. The support centre can not give me a reference number for my call as they get an error when trying to log a call with Openserve... the same issue I had in November... I'm so tired of sitting on line hours a day to try and sort out internet.
