Yeh, I'd never do that personally, but he's more bothered about the hassle of having to sort it out than not having Internet for a bit if it doesn't go smoothly. He already went back to just Freeview for TV, already moved his mobiles to Vodafone recently, and only really needs Internet now for Netflix and the odd bit of shopping.
Thanks for letting me know, guess I'll just wait then.
For your information, my line went live today and I can now access my vodefone account.
