Who called from 3156276066

Missed a call from them, called back line was silent. Hung up called again and got a prerecorded message that this number is no longer in service then line went silent again for 30+ seconds. Obviously some scam playing prerecorded messages trying to get people to hang up. Don't answer they are a waste of time.

Called my cell phone, do v-mail left.   Called number back and got recording that the number is no longer in service.

CID:  Utilities Status.  Multiple calls from this and other numbers, no msgs.  Spoofed number?

Calls 7-10 times a day, when I answer there is silence then they hang up, when I call back it says this Verizon customer cannot be reached at this time
