Hi Mick,
If you don't get a proper reply from them in a few days then it might be worth trying to tackle it from the Philippines end. Send the same email to ManilaVisaEnquiries.manila@fco.gov.uk , tell them that you've already tried to report this to the UKBA in the UK, but as they issued the visa, perhaps they could deal with it. I only suggest this as a last resort because the British Embassy in Manila are quite good at answering emails and even if it's nothing to do with them anymore, I'm sure they will pass it on to the right department.
Iain.
