CCC One Nationwide Mutual Insurance Vehicle valuation using unethical practices and behavior

In February 2016 I was involved in a car crash.  The insurance company declared my Chevy Blazer a total loss.

The insurance company purchased a CCC One valuation report.  The CCC One report had multiple violations of professional ethics.  The CCC company claims they have revised and improved the valuation methodology.  The truth is, they have incorporated unethical adjustments and methodology.

I told the claims adjuster the report was unacceptable, but they insisted the report was "approved" by the Ohio Department of Insurance so I could not refuse it.

The report shows unethical adjustments to the market comparrison vehicles.  Example adjustments include arbitrarily reducing vehicles from dealer value to private-party value or from dealer condition to average condition.   

The report makes reference to "weighted average adjustments."  Those adjustments are unethical and even more severe these adjustments are not disclosed. 

Another section in the report shows what they call Vehicle Allowances.  In my report the vehicle allowances show a credit in my favor, however. there is no evidence the allowances credit is included in the report total.

Bottom line, this report should be legally disallowed on the basis that it violates unfair business practices.
