Virgin Media are crap throughout. They have offers for customers at discounted rates but while they can find you in one way they cannot find you another way and take off the existing customer discount trying to charge more than they should. Getting in touch is a nightmare like talking to a prick wall.
Their broadband regularly breaks down interrupting services and jobs running so they are utter useless - what do you expect from something which has had the “Richard Branson” touch?
