There's certainly a lot more topics like this than just the one listed above (the 4.5 week delay mentioned in the link above is super-fast compared to most topics on here, some of which have gone on for months and months). In fact, the number of delayed cable installation topics on here is certainly well into double, if not triple, figures by now.
You are unlikely to get any reliable answers from VM about your installation as no one seems to step in to control and manage these cases when the installation process goes off the rails. Events unfold in a random and totally uncoordinated sequence of unknown duration.
In the meantime, some things you should consider would to be see if you can 'un-cancel' your existing provider and get onto some kind of rolling monthly continuation in the (very likely) event you are kept waiting a lot longer for your installation to happen.
Contact your local council and find out if a request for a permit has even been made (past topics have used this as an excuse for delayed and an OPs own investigations have later discovered no request for a permit had ever been made).
See if any work is showing here for your street

it is not a brilliantly reliable resource but you could check it anyway esp. if your next scheduled date is only two days away.
Also consider that any schedules VM might give you about your installation are probably not based in reality but simply on the latest bit of automatically-generated information which has popped up on their display screen. There have been past topics where VM tech's have turned up on multiple occasions to install equipment when a cable from the street had yet to be installed.
Your installation might begin in two days time or nothing may happen for months and months. You'll only be certain your installation is actually going to happen when you can see workers digging up the street outside your home.
