If they do not have a physical store front in Nebraska, they aren't legal. I am in Nebraska, so I have called the dept of banking and finance, I was told "internet" payday loans are not legal. Also, submit a complaint to the dept of banking and finance. You can do it online, and also file a complaint with the FTC, what they said to your daughter is also illegal. Provide both the FTC and the NE dept of banking and finance as much information you can. If I recall correctly, since they are not licensed, you only owe them the principle amount you borrowed.
Keep us posted. Or send me a private msg if you need more help. Hang in there.
