Disobliging (9)
I believe the answer is:
unhelpful
'disobliging' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for unhelpful that I've seen before include "Not constructive" , "disobliging" , "Not of assistance, probably the opposite" , "Uncooperative, useless" , "Not co-operative or of assistance" .)
