I filed a complaint with the FTC (Federal Trade Commission) 1-877-FTC-HELP.
They confirmed it is a credit-card scam. The scammers call from telephone number 321-397-2036, and manage to send to your caller ID the fake number 407-000-1234. There is no point in calling them to take your number off their list, or register with the national no-call registry: the scammers are acting outside the law already and do not care.
However, if the FTC receives enough complaints there are more chances that it will be able to legally pursue this organization.
