Flattery will get you anything
I agree few use the phone book itself, but bear in mind we are talking about a private residence, not a business that would be expected to have a website.
Tommy seemed to be suggesting that if Mr Jones moved out and Mr Smith moved in, and Mr Smith started paying the bills, all would be well. However, the line still belongs to Mr Jones and Mr Jones is responsible for paying it if there is a default.
Directory Enquiry services all depend on the digital version of the phone directory. The phone book is a very localised extract from that anyway, so I was using it in the generic sense of "all phone books".
No Directory Enquiry services would be able to supply the correct number for Mr Smith. They would only be able to give the number at his previous address, or maybe he has moved three times so an even older one. They wouldn't know that he was to be found on Mr Jones's number.
Enquiry by address would be a different question. As far as I know that isn't easily available to the public, if at all. Can Directory Enquiries look up by address if you don't know the name of the line owner? Surely the full address only comes into the question if there are two identical names+initials in the directory?
