BEWARE OF SCAMMERS!

I've been receiving several calls from different numbers, lately; and most of the numbers are blocked. Any time I picked up, and said hello, the person hung up right away. I received a call from the #: 12315426784, this morning; not the first time receiving calls from this same number.
According to what I've read concerning this same #, I believe it's a scam. Please help us to stop these people trying to scam innocent people. They need to be punished for their unacceptable acts. Thx
