So I hired a landscaper to to a little grading, lay new sod and build a dry creek bed in our very small back yard. We’d had drainage issues from day one and it was time to fix it 100%. Fast forward to now the job is “done” and we still have places on the new sod where water stands, the drain pipe he birdied is full of mud and won’t drain and the dry creek bed is about 2/3 finished. He offered no solution when I brought up the issues and won’t make time to come see the problems while my wife or I are home. I haven’t heard from him since trying to have him meet at the house and today he resent me the original invoice expecting payment. I tried to call after getting the invoice and got no answer or return call. What do I do?? Most of what he did will need to be redone!
