(i) Most people nowadays want internet, and usually broadband rather than dial-up (makes the install-anway theory potentially profitable)! In England i doubt anyone wants a swimming pool in their back garden - looking out of my window at this very moment gives me that impression anyway.
(ii) A swimming pool is not supposed to be a "transferrable" service/product, but NTL's broadband, to some extent, is. The question is, what happens when it isn't transferrable? Well, when you are investing in anything which is fixed to your rented accomodation, you want to know about the implications when you do move. So what you do is
you ask before you agree to buy such a service/product. What you don't expect is for the supplier to change their story because to me, this is like the company breaking a promise seeing that one person made the promise and another is failing to honour it.
