The complaints filed against providers aren't a perfect mirror of the J.D. Power customer satisfactions scores. Best Electricity Rates, which earned only two J.D. Power Circles and earned the second-lowest score, had only 21 complaints recorded with the Best Electric. But it's helpful to view these complaints in aggregate: Over 50 percent of the 1,119 total complaints fall under "billing" — another reason to seek out a provider with high customer satisfaction in that area in particular.
