As I understand it C&G 2360 is no longer a recognised qualification, 2391 has been superseded by more updated qualifications, so it looks to me (I could be wrong) that the only up to date qual you have is BS7671 17th edition update, which as it has been sai before does not qualify you as a fully trained Electrician. I'm sure there are other people who can agree or disagree, may be that is the reason they have said what they did. When I was working my company sent everybody and their Dog on the 17th, most passed, those that did then considered themselves as Electricians, which, of course as we all know is total carp, sorry to be so blunt, but that's how it is.
