Received a call and said they were IRS wanted me to have my husband call back. The name on the caller ID is Frank Hamilton.

Same here. Then they said "your loan has been approved"

Received a call from "IRS Headquarters in Washington DC". Total BS hahaha

A male with a vaguely Indian accent left this message on my voice mail:
"Hi, this is [???] Brown with the [Internal?] Revenue Service, the headquarters of [Washington DC?]. The reason to give you a call is to inform you that there has been a legal [???] [allegation?][filed?] on your name. The moment you receive this message, give us a call back on my [???] number, which is 202-241-0450. I repeat: 202-241-0450. If I don't hear a call from you, then I will have to release an arrest warrant on your name. So, give us a call back at [???]. Thank you, and have a blessed [evening?]."

I called the number and got a recording that invited me to leave a message for "this Magic Jack customer."

What you have described is an overseas scam. Both my mother and a childhood friend of mine received calls like this. These telemaggoters are targeting vulnerable people in hopes of tricking them into thinking that they are the IRS. Ignore the calls and block them if you can.
