JT Services Lawn Care destroyed my sidewalk and driveway apron when hired to aerate my lawn and would not return calls, Internet

I hired this person to aerate my lawn. He also aerated my sidewalk and driveway apron.  He left without telling me and I made the mistake of giving him a check ahead of the job.  Not that it would have mattered because the cost to repair the damage is exponential to what I paid.  We called and left messages and he never returned our calls.  This year he had the gall to leave us a flyer.  I emailed him and said please do not leave any advertisements unless you intend to repair the damage you caused.  Of course I never heard from him.
