Support service rate farce badly (9)
I believe the answer is:
aftercare
'support service' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'rate farce badly' is the wordplay.
'badly' indicates an anagram (letters in the wrong order).
'rate'+'farce'='ratefarce'
'ratefarce' with letters rearranged gives 'AFTERCARE'.
Can you help me to learn more?
(Other definitions for aftercare that I've seen before include "Follow-up support" , "Support to customer following a purchase" , "Treatment following release" .)
