Really sorry you're having some issues with your phone line, this isn't good.
Are you still having issues with the services now?
Are you plugged into the master socket? It will have a larger socket and contain a logo of Virgin Media, NTL, Telewest or Nynex. Any extension sockets will be smaller and have no logo.
How many pieces of equipment are connected to the phone line?
Check the phone is seated in the base unit correctly & powered ON. Remove all other equipment connected to telephone sockets.
Unplug the phone and check another phone directly into the main socket ensuring this is a VM socket and not one with a BT or Sky logo. If no alternative handset is available then ensure
the original phone is plugged into the main socket with no other pieces of equipment being plugged in.
