New 360 Box with no connector cable adaptor

Hope someone can help me here (edited as I finally got through to someone but I have no idea if he understood me and ordered the right thing)

I have just received a new 360 box to replace our old Tivo, but it hasn't come with a connector cable adaptor which is needed to connect the exiting white connector (coax) cable to the new TV box.  To clarify, we didn't have an adaptor to connect the old Tivo box, as the install is that old.  Can anyone in Virgin check that the correct adaptor is being sent to me, at one point he was placing an order for a new power adaptor!
