Also received the "You've been upgraded" email today my.virginmedia.com still shows me as "Broadband package: 2Mb M" and speedtest confirms.
I registered months ago for the upgrade and was informed a new modem would be with me in 5 days. /sigh
I have contacted the "Web team" who assure me my old modem (NTL home: 120) is capable of 10MB+, it irks me slightly that a neighbour who has the same modem and didn't register for the upgrade has been on the new speed for weeks now.
I guess old habits die hard with this company!
