Very bad service area? Just the opposite (4,5)
I believe the answer is:
vice versa
'just the opposite' is the definition.
(I've seen this before)
'very bad service area?' is the wordplay.
'very' becomes 'v' (abbreviation).
'bad' is an anagram indicator.
'service' anagrammed gives 'icevers'.
'v'+'icevers'+'a'='VICE VERSA'
(Other definitions for vice versa that I've seen before include "film" , "With parts the other way round" , "otherwise" , "With the order reversed" , "The other way around" .)
