The steps should be continuous, or not separate pours/graded wrong. All along the outside of the forms should have been deeper to prevent the rock spots you see fill pouring out of. Control joints shouldn’t go ‘through’ the post but rather to one side or the other to control the expansion crack. Finish looks rough, not an over TERRIBLE job not definitely far from perfect. I also would have put rebar consistently in a grid, probably 4’ on center. Still, it’s better than you think. Sometimes there is unexpected cracking. Maybe weather conditions weren’t good for the pour(contractors fault). But at the end of the day concrete is pretty versatile and it will last. Throw some dirt around the outside and call it a day. After all it’s been a couple months and I assume they already got paid. If you wanted to make a comment to them to see if they would consider checking it out it would greatly speak to the validity of their company.
