We have a bit of a Catch 22 situation in getting our VM connection and wondering if anyone can advise.
Details:
We've just moved into a new build house. We had VM coax run to rooms we may want a TV point in, as advised by our local VM new build guy.
The coax comes out of a hole/socket in each room where we want TV points.
I gather that the other ends of each piece of coax should have been terminated outside the house, so the outside engineers can attach it to the external VM brown box via a splitter (that's what an outside engineer told me today anyway).
However: the builders terminated the coax in the hallway inside the house, right by the other side of the wall where the external brown box will be fitted.
See photo.

(By the way, there's too much coax there, we only need 3 TV points so we'll cap the rest).
My question is: how are we going to get the coax inside connected to the box outside?
Sure, the coax is plenty long enough to reach, there's loads of length. And I know it's a matter of making a hole and pulling it through.
But the problem is...
The outside subcontracted engineers won't touch the inside of the house - they just expect the coax to be sticking out the outside of the house for them to pull the cable through the ducting outside and install the brown box.
But until they've been and done their bit, the inside VM engineers won't come. But the outside guys tell us the inside guys have the tools needed to do this internal work.
And to be clear, no-one's done any work yet. We don't have an outside brown box. But we DO have the ducting installed from the main trunk sweep to the house.
We're so close! Wondering can anyone advise the best way to approach this? Should we just call VM tech support and explain the situation? I admit, I hate calling them cos I can wave good-bye to an hour of my life each time.
Maybe we need an inside engineer to come first, then the outside engineer, and then the inside engineer again?
Thanks for any advice.
