Perhaps the arborist who's been there will still come through... i am just a homeowner, and i have observed tree-folks are not confined to 9-5pm-job-mentality... plus, if a tornado came through recently, he's probably working constantly as you weren't the only one with damaged trees...
as to going to court, if you didn't have a written agreement with the 'tree trimmer,' i ponder how much of a settlement you can get from someone you hired without seeking his credentials/skill level... after reading this forum for 10 months, i have discovered how naive i am... when i first got here, i thought tree-trimmer=arborist, and i have been taken to task more then once by this crowd... :biggrinbounce2: and rightfully so, now that i have the vague beginning of an education as to what to seek in someone to work on my trees...
good luck on your trees...
