The comments here do point to fake "legal settlement offer" calls regarding medical claims. It's advance fee fraud by any name. In the US if you win a damage award as a plaintiff or a class action member, you *DO NOT PAY TO COLLECT* that award! Your legal notices are not going to come through mysterious phone calls from incomprehensible cretins in South Asia.
A person called from this number claiming to be from visa saying that I have a balance due of $1300 and wanted me to make a payment with another credit card. I laughed and hung up. They then called back claiming that they were from a hospital and that I needed to make a payment. The number was the same as the number for the visa caller, both spoke with a thick accent.
they probably get good numbers off of the DO NOT CALL LIST and since they are spoofing someone elses number or a disposable cell phone , they are hard to stop.
best way is to answer it like you are a police dispatcher and they have called the non-emergency number, or some other city or county office
or just keep asking them DO YOU KNOW who you called ?-- this is GOD-- REPEAT OVER and over UNTIL THEY HANG UP. never verify someone at the number they reached has the name they are using! DEFINITELY FRAUD/SCAM time for us to abuse these losers
tell them they are under arrest, and then tell them they have no rights ,
record their call or one of those credit card recordings and play it over and over. speak to them in a made up language ,that no one can understand , hamma hed tuurarer daswer wasraw morting guty runking mutter futter gumby has some gum for you and yo mutta.
One more time, a national registry of phone numbers with NO names attached, no demographic data, no mention of income or occupation or anything, is the dumbest place for illegal sales and scam callers to go mining. Lead generation and the steady trade in contact data have existed long before any opt-out list was ever conceived.
