Just called Virgin Media to check how much it would cost to upgrade from my 10mb to 20mb connection, the answer I got was that I would get an £8 reduction on my monthly bill. I currently have a XL pack for TV with M Phone Line and V+.
They're also giving me a free wireless router and upgrading my dated NTL modem.
Lucky I called them !
Really just a heads up for existing customers to get an upgrade and save some money too. How else would they find out !?
