I think the problem from a lot of the VFS offices is that they'll say you must submit the appendix with height and eye colour and then they're not even specific about how to get that appendix or what is in it, let alone actually providing it to you. (It also doesn't help that there are various appendices in different forms so naming isn't terribly consistent - we complain about the clunky names of imm0008 etc but at least those are consistent, mostly).
What is on the Appendix A you got?
Anyway, let others know how it works out, whatever you do.
