now there's no reason not to leave the rapidly degrading Virgin media
Just moved into a new build house and found that my phone line wasn't connected and BT were going to charge me £120 to flick a switch, tried other Networks but basically had to go through BT. At the time I was also interested in getting Sky so I rang them and they informed me that they would credit my account with £120 if I was to go ahead and get Sky which I did.
Since then my Sister has also used this deal and we also got the refer a friend £50 Marcs and sparks vouchers.
