Luyện ngữ pháp - English Grammar in Use - Intermediate (Unit 46: Have something done))
Study this example situation:
Lisa had the roof repaired yesterday.
This means: Lisa arranged for somebody else to repair the roof. She didn't repair it herself.
Be careful with word order. The past participle (repaired/cut etc.) is after the object:
Get something done
This does not mean that they arranged for somebody to steal their bags. 'They had their bags stolen' means only: 'Their bags were stolen'.
