Just called tech sup. A helpful tech talked me through upgrading on the NTLworld site via the My Accounts option. It came up with an error that seemed to surprise him. He told me to call back in a week if it hasn't happened automatically.
I just tried again on the NTLWorld page and it worked...but only if you tick the T&C box.
Now on 2Mb in Hemel Hempstead. I dont know what area that is for the vote in case anyone can enlighten me.
**apparently I am in Langley...and I have voted.
