Who called from 5713488378

Calls often. Hangs up while I say put on do not call list. I called back and said it again and was hung up on. Calls every day sometimes

Just ANOTHER law enforcement benevolent charity scam where the scammers retain 99.999% of the donation for their effortless effort.  Told them I was busy but he kept with his script so I triggered my smoke alarm I keep by my phone for calls like this.  Told them I could either put out the fire or talk and he hung up quick.

I got a call from this number today - I said hello and they hung up ? When I googled the number it said invalid number ? -scam I guess ?
