Rebuff; rejection (7)
I believe the answer is:
refusal
I believe this clue is a double definition.
'rebuff' is the first definition.
(I've seen this before)
'rejection' is the second definition.

(Other definitions for refusal that I've seen before include "Possibly first option to buy" , "Indication of unwillingness (to do something)" , "Turning-down; denial" , "Negative response" , "Rejection; turning-down" .)
