When you call VM for updates, the person you are talking to has no idea at all what the status of your job is. They are simply reading the next scheduled date on their order management system. The phrase that customers keep reciting on here is that the agent will 'guarantee' the installation will take place on the next given date but the guarantee has no value to it at all.
You might find some info on here ref street work (assuming VM's contractor has applied for such work) but not all work is listed reliably

use the drop down box under search for any future scheduling. You can also try phoning your local highways authority (which might be your local council or county council) and ask if VM has applied for any permits for street work (if that is the line VM is giving about the delays).
In reality, your job is likely to be delayed on cost grounds until someone works out what is involved and required to do the work and whether your job is within the allocated budget. Until that happens you will wait.
Keep detailed notes as you go along of everything that has happened as you will be eligible for compensation for the delay

once you are connected.
In the meantime (if you currently have no connection) look into some sort of mobile connectivity on a rolling monthly basis to keep you going while you wait for VM.
