Thanks Arthur.

Just to note you can change your appointment date by going to visa4uk website. log in and click view appointment. If it's more than 5 days ahead then click update appointment.

I think it's ludicrous that there is no phone number for VFS global centre in cebu. The same place deals with visas for Canada, Australia and the USA. Possibly other countries. There are telephone helplines for these countries at this centre but not for the UK.
