Cant comment specifically.....
...but in general if you need a new cable to be pulled from the street cab to your property they pass through a quite narrow duct which can often get blocked by old cables, collapsed duct etc. If thats the case then they need to inform/apply to the council for a permit to dig the street or road to unblock it. That process can add a few weeks or a month or two before the permit is issued, the digging is done and the cable repulled - as it involves several 3d party and VM teams.
