Or for me, accidentally cut the copper line to the rest of the neighborhood and had to dig a trench in my front yard to repair it. I'm on the corner and towards the front of the subdivision, so I had quite a bit of work being done over the past 6 months.
And they leave a pile of dirt, plant the wrong grass sod, put the sprinklers in the wrong place, and then tell you that they are done because it's just "cosmetic" issues left? Sounds so familiar.
They cut my neighbors water main in the process, and then blamed it on inaccurate (spray painted) markings. I'm a novice, but even I could tell that the markings were accurate. They also managed to put a speed bump in his driveway when they were tunneling under it - big enough to spill a beer. I got pretty lucky with my dead grass and misshapen tree rings.
