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.

The Consumer Financial Protection Bureau on Thursday ordered payments firm Block to pay a penalty, citing fraud and weak security protocols on its mobile payment service Cash App.

Block has agreed to pay $80 million in a settlement with dozens of state regulators over alleged problems with its program to counter money laundering.
