I had used David Schaefer Septic Services 2 years ago pump out my septic tank and hired him to add a riser to my lid. He pumped the tank out but never came back to do the add the riser. I just filed it after 1 month and dealt with it. This week I called him as I needed a pump out, and he said he could do it Friday afternoon. So I took off from work. He never showed or replied to my voicemail. I have to say stay clear from this dbag.
