The lengths scammers go is insane

How is there not more legislation banning such practices to steal confidenial or financial information from people. Its to the point where you can't dissertain real agencies with fake ones. They use the same voices, same numbers, same emails, and already have personal information on you! The other day i received 3 phone calls from a healthcare company ive never heard of, claiming i need to file a claim so they can process a visit i did have last summer! They called again and i gave them my info and i think it was a scam. Makes me never want to respond to anyone whether its legitimate or not!
