You're certainly on the right forum! VM seem to be having some problems with this type of installation work at present.
Unfortunately, the current process for actually getting a cable installed does seem to be via a random sequence of actions on the part of VM and its sub-contractors. Only when the sequence of required tasks randomly, and by chance, happens in the correct order does the cable get fitted! This often seems to involve technicians turning up to install VM services when no cable has been installed or VM employees turning up with no idea why they have been sent to the job or planned visits being cancelled at short notice and moved weeks into the future. Sounds like you already have experience of this.
Take a browse through the other topics on this forum and you will find multiple posts involving the issue of delayed cable installations and you'll get a good idea of the general pattern of chaos when it has gone wrong.
One of the VM forum team will pick this up in a day or two. I would normally say they will be able to help you but often on these topics they too seem to be limited in what they can do to push things forward.
(On a slightly more encouraging note, if you really do actually have the cable in place from cabinet to property then that 'should' be the worst of the task done)
