Scold for ordering rebate (6)
I believe the answer is:
berate
'scold' is the definition.
(I know that scold can be written as berate)
'ordering rebate' is the wordplay.
'ordering' is an anagram indicator.
'rebate' is an anagram of 'BERATE'.
'for' is the link.
(Other definitions for berate that I've seen before include "Scold harshly" , "Censure severely or angrily" , "Reprimand" , "Angrily scold/criticise" , "Scold, censure" .)
