Best Directional Drilling in Cleveland OH

Called out to inspect drain in walk out basement doorway to see why it was overflowing into basement. Inspected using previously installed clean-out and through walkout drain. Told me pipes were mostly clear but they couldn’t jet due to previously installed corrugated tubing. Also told me drain pipe was different than gutter downspout piping. I told them previous plumber said all pipes ran together but they said I was wrong and the previous plumber was a “hack”. I just ran water through open gutter pipe and observed water moving in drain pipe. They are all one system.
Professional in the beginning, but quickly turned arrogant when questioned about job.
