This scammer calls numbers on the national do not call registry in violation of the Telephone Consumer Protection Act. They further violate the TCPA by refusing to provide a physical address when asked. They claim that there is a problem with your merchant credit card processing account, but can't elaborate on what the problem is, why they think there is a problem or even if you have a merchant credit card processing account! This is clearly some kind of scam, since they clearly don't know what the problem they are calling about is and are completely unable to articulate why they are calling, but they definitely want financial information. Do not provide any personal or financial information to this scammer.
