I have found the link on their FAQ - "If you have booked with us direct, please contact P&O Cruises to advise of the correct details on 0843 374 0111 (Calls cost 3p per minute plus your telephone company’s network access charge). " - but nothing to tell me the opening hours of this line, can anyone confirm?
Pretty sure the office wouldn't like me phoning from work tomorrow so it'll have to wait until I get home, just hoping it's not a 9-5 line or anything. (Or maybe the freefone number in the stickies is one I can use? Then I could do it in my lunchbreak)
Thanks for the help
