As you said in your earlier posting, this is a great faff each time.
I take it you are still waiting for the 2nd from Haringey?
Does the same CAD number apply to separate incident in different location?
EDIT - I've re-read the text message from the Met in your Haringey thread. So it does apply. I would attach a copy of the Met text to this rep and the Haringey rep and any future reps)
Have you checked Enfield for any additional PCNs?
