There is no other option but to get a technician out to you.
Although I'm sure that VM would most certainly like all of their customers to move their phones next to the hub as that would be by far easier and cheaper for them, they are obliged to come out and run extra wiring between where the phone is now ad where the hub is. In this way the phone is connected to the hub (and that bit isn't negotiable, it's the way it has to work now), albeit via a long extension cable!
Depending on the layout of your house, it may be possible to run this externally, roughly following the paths that the existing phone wires and coax cables take.
The delay in getting someone out to you does sound a bit excessive, you wouldn't be able to receive calls as well as make them if the switchover takes place anyway but the phone isn't connected - hopefully a member of the forum team here who are VM employees may be able to sort out an earlier one.
