Dear Jacqui,
I don't know where you live but I do wonder whether:
1. there might be a general community service organisation locally which might be able to help you with your quest,
2. there might be a community legal aid, or community legal advice, service locally which might help.
I am in Australia and I would think that here (apart from Googling) it would be a good idea to look in the early pages of the telephone directory for possible sources of assistance. Or approach your local Council or your local MP - and persevere (especially with the latter) if you keep getting fobbed off.
You seem to have been quite inappropriately fobbed off to date. I think the advice from 'behind thefrogs' and your own ideas are excellent.
I wish you good luck in your search while warning that any information you find could be disturbing - so persevere only if you are prepared to deal with anything you find.
Very best regards,
JAP
