"Bey", he calls out, "complains repeatedly!" (10)

I believe the answer is:

bellyaches

I'm a little stuck... Click here to teach me more about this clue!

'complains repeatedly' is the definition.
'bellyaches' can be an answer for 'complains' (bellyaching is a kind of complaining). I'm not certain of the 'repeatedly' bit.

'bey he calls out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'bey'+'he'+'calls'='beyhecalls'
'beyhecalls' is an anagram of 'BELLYACHES'.

Can you help me to learn more?

(Another definition for bellyaches that I've seen is " Complains".)

I've seen this clue in the Sydney Morning Herald.
