What socket (if any) do you have? It's not at all uncommon to see a socket from one of VM's predecessors such as NTL or Telewest, and if one is present you try and connect to it. Sometimes there is just a coaxial cable poking throught the wall, so try that one. If all fails VM will supply and fit one at no cost to you.
