Freeview only comes through an aerial. If you haven't got an aerial socket you can plug it into, you can buy an indoor aerial quite cheaply (from Argos, Tesco etc). It may be a little hit and miss how good the reception is though - generally the higher up you are, the better. However modern TVs do seem to be better than old ones coping with poor signals.
Alternatively you can just connect to your cable service. I assume you are with Virgin - I seem to remember they will provide you with a basic box that will provide all the Freeview channels (give or take a few) for an extra £1 a month. It is also worth considering their basic Tivo package which allows you to record, pause live TV and watch stuff you've missed on demand
I wouldn't return the TV - all sets come with Freeview built in these days - it doesn't stop you using cable
