Best Sewer Line Hydrojetting in Denver CO

My mom had a leak with her garbage disposal. She found these guys in the Christian Business Directory. Said they would be there on Monday between 8 and 10 am. She called them at 10 am  and they said there was an emergency and the plumber would be delayed. They showed up at 4:30 pm. Meanwhile, she is hosting relatives from overseas so this completely ruined a whole day.

Oh, and when the guy finally shows up, he looks at the garbage disposal and says there's no leak. My mom runs the water, the water leaks. . .

At least he fixed the leak. I have rental properties and looking for good help. I would definitely not use or recommend these guys.
