Totally disorganised (7)
I believe the answer is:
chaotic
'totally disorganised' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for chaotic that I've seen before include "Disorderly, shambolic" , "Confused, disordered" , "In complete confusion" , "in random order" , "Topsy-turvy" .)
