Fill in the blank with the correct preposition: ‘He complained ___ the poor service.’

Explanation

The verb ‘complain’ is conventionally followed by the preposition ‘about’ when describing the subject of the complaint, as in ‘complained about the poor service.’ Note that ‘complain of’ is sometimes used specifically in the narrower context of physical symptoms, as in ‘complained of a headache,’ making ‘about’ the correct general-purpose choice here.
