Apropos the post about missing/duplicated districts in the GRO's Historical births and deaths indexes, have I mis-remembered this. . . . .

Someone, fairly recently, said that they'd ordered a certificate/PDF from the GRO. I can't remember if a certificate was sent but it was the wrong one, or if the GRO said that the reference was incorrect and that no certificate existed for that reference.

Are you that someone? And if so, can you either point me to the original thread, or else summarise the story again, please?
