Allstate accused of charging 'sucker' customers higher car insurance premiums

US insurer Allstate increased premiums for customers already paying the highest rates for their insurance, while keeping premiums more or less the same for 'thriftier' customers.

A joint investigation by The Mark Up and Consumer Reports found that Allstate devised a 'customer retention model' or 'advanced' price adjustment algorithm that identified existing big spenders and squeezed more money out of them than others. 

The algorithm also determined customers which customers were owed discounts. Though some customers were owed thousands of dollars, Allstate capped the discounts at a half percent irrespective of the amount owed. Senior customers were overrepresented within this cohort.

Insurers are not obliged to inform customers if they are denied discounts, and the National Association of Insurance Commissioners told The Markup that it had never heard of an insurer voluntarily informing its customers that they had been denied a discount. 

Maryland rejected Allstate’s proposal on the grounds that it was discriminatory. However, it was approved by Arizona, Arkansas, Wisconsin, and a number of other US states.
