A Philadelphia-area attorney has filed a class action suit against Microsoft, claiming the software maker ripped him off after he bought points that were supposed to allow him to make purchases over the online Xbox Live Marketplace. Samuel Lassoff, of Horsham, PA, said an invoice he received earlier this month from Microsoft included charges for purchases he couldn't complete due to a balky download system—and he claimed it wasn't an accident.

icrosoft "engaged in a scheme to unjustly enrich itself through their fraudulent handling" of his account, Lassoff charged in papers filed earlier this week in U.S. District Court for Eastern Pennsylvania. Microsoft allows customers to buy games and other downloadable media from its Xbox Live Marketplace with "Microsoft Points" that users must purchase with real currency, typically through a credit or debit card. But Lassoff claimed he and at least "hundreds" of other Xbox Live users have been overcharged. "Microsoft breached that contract by collecting revenues for digital goods and services which were not provided," Lassoff said in his lawsuit.
