Bothered by a mess in consulate (7)
I believe the answer is:
embassy
'consulate' is the definition.
(I've seen this before)
'bothered by a mess' is the wordplay.
'bothered' indicates anagramming the letters.
'by'+'a'+'mess'='byamess'
'byamess' anagrammed gives 'EMBASSY'.
'in' is the link.
(Other definitions for embassy that I've seen before include "Diplomatic organisation" , "diplomatic venue" , "Headquarters of diplomatic staff abroad" , "Office of an ambassador" , "Foreign Office" .)
