This scammer calls mobile phone numbers without pre-existing permission from the recipient in violation of the Telephone Consumer Protection Act. They further violate the TCPA by failing to have an operator on the line when the call is answered, and still further by playing a recorded message without an operator on the line. They fail to provide a phone number and address when asked, yet further violating the TCPA. Their recording states that the victim has been selected to have their student loans reduced by 50% and the remainder reduced to a 0% interest rate. This is clearly a scam as the phone number they called has never been associated with a student loan, and the victim has no student loans. Do not provide this scammer with any financial information.
Lots of places use the "Do Not Call Lists" as a list of numbers that are valid phone numbers, instead of dialing random series of numbers. Putting your number on a do not call list is pretty much a guarantee of getting more calls.
