Worst service

We have requested an address move and waited almost 3 weeks for the fibre to be installed at the new address. Now the fibre is installed for more than 24 hours but it is still not activated. When we speak to the consultants at metrofibre we are being told that they do not pick up our ont on the system. We have been told for the 3 times that it has been escalated with no further feedback. When will this be resolved? Now we are paying for no internet and have to keep on buying data so we can just do work from home. This is unacceptable!
