About past perfect:

• Past tense / Simple past tense is a tense used when we talk about something that happened in the past.
• The tense lies in the modification of verbs in the sentence. (Eg): She writes beautifully. (Present tense) When the verb 'writes' is changed into past, it becomes: She wrote beautifully. (Past tense)
• Past is a verb tense used for a past activity or past state of being.
• Past perfect tense is used when we talk about something that had happened even before a past. (Eg): The tiger had eaten (past perfect) its prey before the lion arrived(past tense).
• Past perfect is used to show that something had happened before another action in the past.
• Past Perfect is formed by 'had + past participle'. Thus the verb 'heard' becomes 'had heard'.
• Therefore the answer is: I had heard a complaint from their sweeper.
