Who called from 9379647002

Wanted to send me a check for 50.00. Nothing is free in this life so I know it has to be a scam.

keeps calling and hanging up

Calls collect four times a day and hangs up.

Calls multiple times a day.

I keep getting calls from numbers I don't know.I did answer 2 of them one number hung up when I answered only rang 3 times.Another one when answered gives a reference number but can tell it is a recorded message when you answer it and I got this one today with this number but none of them leave a message if they get the voice mail,they just keep calling
