Isn't it a pity that, with Virgin, such extreme lengths have had to be used to get some information which is a customenr's legal right - but of course divulging it means that Virgin can now loose a customer. I have never needed to ask my ISP, Plusnet, for my MAC number as I have never had a reason to change to another ISP. I know which ISP I will now never touch with a bargepole should I ever wish to change.
P.P.
