Who called from 4246724427

I've been getting somewhere between one and five calls a day from this number and every time I answer it hangs up. Wth.

This number calls me all the time and no one is ever on the line. When you call the number back, it says it is a number that is not in service.

this number calls me over and over, when I answer there is some noise and then hangs up.

Keep calling and don't say anything

I keep receiving phone calls from this number and they never leave a voicemail. When I call them right back, there is a beating noise and then it states that the number has been disconnected.
