That phone number might not be his or owt to do with him. Just did a search on it and it appears on a well suss website.
Searched my mobile number on google, nowt came up - searched my wifes, up pops her number on that website with complete ballcocks details - she's held the number for well over 10 years and I've been a/c holder for it for at least 10 years!!
So I'm afraid that'd be possibly a dead end, well the web****e thing anyhows...
