18 months waiting for install

I've been with Virgin Media since they took over NTL some 20+ years ago.
One house move and everything falls apart.

Moved Aug '22, was told 2 weeks install. That turned into 5 months of cancelled appointments, repeatedly stating 'still need to do outside work'.
Finally did the work outside and still kept cancelling due to 'need to do work outside' 🙄

Then all communications ceased Jan '23.
They've forgotten about me.

So I come here and post, a mod picks up the thread to 'look into it' and go figure...never gets back to me.
So I try calling them on 150 from a friends phone a few times over the months - 2 agents don't understand me and keep trying to set up a new account.
1 agent thought I was trying to make changes to the friends account/phone I was calling from.
1 agent understood me and left me on hold untill i disconnected.
Few times just sat on hold..

The worst thing is they have (had?) my landline number as I wanted to keep it - I was on the waiting list for an ASD assessment which takes on average 5 years. With only my landline to contact me, I've very much missed that so I'll have to reapply, and wait another 5 years 😫

I've had a cheap connection set up with someone else in the meantime - My cheap 'temporary' 12 month contract with them just expired 😂

I don't know where to go from here. I want my connection back but after a year and a half they still haven't run a cable from the road to the pre-drilled hole in my house - how do I make this happen? Can it still happen?

Is there a direct telephone number or email I can use or something? Phone and forums have both failed so far.
Do I just bail on VM...

Any advice appreciated, I literally haven't got a clue what to do about this..
