Said and done in making a complaint (8)
I believe the answer is:
adenoids
'said and' is the definition.
I can't judge whether this definition defines the answer.
'done in making a complaint' is the wordplay.
I cannot really understand how this works, but
an anagram of 'done' is 'deno' which is within the answer.
'a' is within the answer.
The remaining letters 'ids' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for adenoids that I've seen before include "They affect the voice" , "Enlarged spongy tissue between back of nose and throat" , "Enlarged spongy tissues between back of nose and throat" , "Lymph tissue towards back of throat" , "These in the throat aided son" .)
