I keep getting calls from this numbers sometimes 5 -6 times a day

I keep getting calls from this numbers sometimes almost every day.

Calls and hangs up. Never leaves a message. *Spoofed number.* When you call it back you get a weird ringing sound followed by a message saying that the number is not in service.

This guy calls several times a day. I finally picked up and he asked for the parent of my son. When I said 'speaking" he just hung up. I just wanted to curse him out. When I called back I got the funky dial tone.Just blocked his number altogether.

Got a call from this number I answer,  this guy wants to speak to my granddaughters parents, I asked who it was, he hung up I tried calling back but got a funky message
