I agree that it is rude. Regarding names etc. all cases are available on a public register so that anybody can access the case details accordingly. Similarly, anyone can attend a hearing which is open to the public.
I would write back and tell them that they have enough staff to issue tickets! and that they are quite dysfunctional, like Barking and Dagenham.
Also, they had enough time and staff to issue a NOR. I have had dealings with this mendacious outfit.
Perhaps they should take stock?
