Singapore Airlines (SIA) doesn't seem to have a dedicated, walk-in office in Liverpool for UK-wide bookings, support, and general inquiries, you should use their Singapore Airlines contact center at +1-866-829-1086 (24/7) or visit their UK Contact Us page for email/writing options, as the "Liverpool Office" references online often lead to generic numbers or irrelevant locations, not physical SIA branches.
