They [the scammers] say they're from the government and that, using the Affordable Care Act as a hook, they need to verify some information. They might have the routing number from your bank, and then use that information to get you to reveal the entire account number. Or, they'll ask for your credit card or Social Security number, Medicare ID, or other personal information.
I've said it before and I will say it again -
Even if they say they are from the government….
Believe me, the government already has your information!
