The new US consumer agency is already facing pressure from different sides on how best to set up such a service, Bloomberg reports.
As part of the Dodd-Frank overhaul, the Consumer Financial Protection Bureau is required to come with a means by which customers can submit their problems with regards to products and services.
While some groups - such as Consumers Union and Sunlight Foundation - are seeking an open system, others, including the American Bankers Association, want to keep it closed.
Richard Riese, senior vice-president at the association's Center for Regulatory Compliance, said: "The point of banking supervision is to get the system working properly, not to air dirty laundry and scare capital away from banks."
Bloomberg recently reported that a number of US banks have offered billions of dollars to settle a probe of their foreclosure practices by state and federal officials.
