Is the treatment for Emerald Ash Borer killing our Ash tree?

We asked certified arborist from a reputable company assess the health of a very large ash tree in our backyard. He said the tree was "very healthy" but that we would soon need to begin treating it against Emerald Ash Borer. We are in the midwest and the pest is getting very close to our location. He said the treatment is 99% percent effective when started early enough, and that it will have to be done every-other year indefinitely.

The huge tree is the centerpiece of the yard and shades the entire house, so we opted to begin treatment this year at $475 as a preventative measure. They came out a treated it eight days ago, drilling a dozen-ish holes in the trunk and pumping some chemical inside. Now, the leaves are curling up and dropping like flies. The driveway is covered in them.
We have left a message with the company to come out and assess the situation. The arborist said nothing about potential side affects or risks. Could they have pumped it full of the wrong chemical? Can anything be done to fix it? If this goes very badly, how would one assess the value of a mature tree for insurance or small claims court?
