Court says Dell's three-week robodialing spree should have stopped when woman asked | The Verge

"The suit was raised by Ashley Gager, whose cellphone Dell used an automated dialing system to call approximately forty times in a three-week period. While Gager had previously allowed Dell to call her, she later wrote the company a letter asking that her number be removed from its database, but the company refused. Dell argued that the Telephone Consumer Protection Act of 1991 (TCPA) didn't afford Gager that right, but the court disagreed. In part, the court came to that conclusion on the grounds that consent — as it's held to be elsewhere in the law — is revocable."
