It is terrible but people just don't care as long as they can get their hands on your money. If they can't con one they just keep moving along until they find those they can fool. It is scary because some of these places are getting more sophisticated in trying to sound more realistic which is why its easier to just hang up on them and not bother with them. There are phone numbers you can report these scams. The IRS website has phone numbers and emails you can send information too. I hope your Dad didn't lose money.
