The drainage ditch is too deep in the middle

Drainage ditch too deep
The previous owners destroyed the natural drainage away from the house years ago when they added dirt and planted a large tree. The ground surrounding that tree slopes back toward the house on the one side.

Over the years, rain running off the roof made a trench that held water from both the roof and that slope 7 feet from the house back towards the house. I'm trying to repair that situation now, and told a man to dig lower than the trench to move the water from the house to the street. He dug about a foot farther out, but made it too low, now water will till pool there, (but it is another foot from the house.) It did not have to be made that low. His repair is sort of parentheses shaped, with both ends being higher than the middle, and the water can't flow away until it gets filled.
That now needs fixed. Will having him just put dirt and gravel back in that too low area do the trick, or what needs done now? Do I need to get a landscaping company in here?
Thanks.
