I want to publicly express my appreciation to the NYS Department Of Financial Services for their help with Banco Popular (a. K. a. Popular Bank). Banco Popular had already thumbed their noses at a complaint filed with the federal CFPB (Consumer Financial Protection Bureau), but the complaint I filed with the NYSDFS got results - the Banco suddenly had a change of heart!
The reason I'm giving 4 instead of 5 stars is because the NYSDFS didn't confirm with me that the problem was resolved; they just closed the case after hearing the bank's response. It's better to "close the loop" and confirm with the original complainant that the problem was actually resolved.
