Berlin Bob - do you think it could be done a bit like the SIT?
in theory, Yes !
in practice - is it sensible ??
Basically you are asking for a list of ROs with service details included (Date ordered, Date received, Photocopy or hand written, Helpfulness of staff)
Lists of ROs are available elsewhere, with addresses, opening times, telephone and e-mail.
So, how constant are the service details ?
Good service one week, then BBC does a repeat of "Who do you think you are" and the service is slow for several weeks, then good service, then summer holidays, then .... etc.
It would be easy enough (relatively speaking) to make such a list but who would maintain it and how ??
