Cash App-owner Block must offer up to $120 million in refunds to consumers who federal regulators say were exposed to potential fraud.

The Consumer Financial Protection Bureau (CFPB) announced today that's it's fining Block, the creator of Cash App and parent company of Square, $120 million in "refunds and redress" and a $55 million fine for how the company handled fraud on its payment platform.

The CFPB is also ordering Block to fix Cash App’s customer service and its processes for investigating disputed transactions, in part by setting up 24-hour, live-person customer service. The order requires Block to fully investigate unauthorized transactions and to provide timely refunds when appropriate.
