If it is a genuine number used by Virgin, why he did not tell me more the details and hung up. Is this your Virgin Media's usual way?
The number may be linked to Virgin Media but you have no way of knowing if the call was genuine or not. Scammers regularly fake the caller ID so that it looks as if the call is coming from somewhere genuine when, in fact, it is not. You have no real way of telling who the call was from just from caller ID alone.
As has been suggested at message #2 above, you are better calling in yourself to find out what might be on offer for you.
