I'm not saying to chew them out, but call and speak to the owner/manager, and them they're not doing all the trimming, and are missing places when they mow. My mother used various lawn services for over 30 years, on both her, and my grandmother's place. My grandmother had an acre too. There were a few that she stuck with for several years, until they either went out of business, or got too expensive. There were a few, over the years, that did thing like what you are experiencing. She'd call, and only speak to the owner/manager. A few times, that did not solve the problem, so she fired them. On at least 2 occasions, the owner had hired someone, and didn't know they were not doing their job well, until the complaints came in. They got it resolved quickly, and she used their service for quite a few years. In at least two instances, they had hired someone new, and when complaints kept pouring in, they let them go. You won't know though, until you call, and let them know.
