As both services are still "live" I would assume that both listings will show so it should just be a case of changing the order.

I can see two ways round this and the first is to go ex-directory for the NTL one to prevent that being given out.

Or possibly talk to BT to get them to treat your account as if it had just been created as a new number as I would assume the rule applied is the latest number associated with your name/address is the one used by all the various directory services which AFAIK all now connect to the same master database or at least all have their data base fed from the same set of individual companies.

This is all just a guess though to give you something to try.
