VM cannot/will not, pull cable through the BT service ducting.
You need to contact moves and transfers, if your new address has been registered with Royal Mail, they should be able to create the address as serviceable.
From experience this may take a while to sort out, so contact them sooner not later.
Have you rung sales to see if your address is on VM data base? And if it is what serviceable status is it at?
You've stated that there is a cable point within the property. How do you know its cable?
you could get it surveyed. use this form
