Yes, but the sales process instead does a check for "has this property been connected before", and assumes there's a socket and all is connected and serviceable. As you've found that's a dodgy assumption, because not everybody is willing to leave VM's wires and sockets in place after they've chosen a different ISP.
Best to phone up and try and book a technician installation. If the outside cables have been removed as well, then you might need a cable "re-pull" and could then be looking at several weeks or even months of delays. Fingers crossed it's quick and smooth, but consider the possibility that it won't be.
