Rebukes salesman, as chore goes wrong (10)

I believe the answer is:

reproaches

'rebukes' is the definition.
(reproach is a kind of rebuke)

'salesman as chore goes wrong' is the wordplay.
'salesman' becomes 'rep' (I've seen this before).
'goes wrong' is an anagram indicator.
'as'+'chore'='aschore'
'aschore' with letters rearranged gives 'roaches'.
'rep'+'roaches'='REPROACHES'

I've seen this clue in The Telegraph.
