So the address option thinks you are close, but the two sets of ADSL Max estimates very different. Errrm - how long has the phone line/number been installed? That can take a few days to update if it is new. (It gives the data for the previous premises it was used at).
Unfortunately, if that's the case it would be the address checker that is right
