Who called from 5156484137

Three missed calls from this number, no message.  When trying to return the call, get a Verizon recording saying it is not a valid number.

This number has called my wife three times no one on the other end. When calling back get a message not a valid number

Got woken up by a call from this number. Didn't recognize it, so I let it ring until I would receive a voice mail, but nothing. Never called it back, instead looked up reversed number, and am glad to find this is a scam number.

After two rings, I answered a call from this number (because it was a local number) to hear only silence on the other end. When I tried to call it back, a recording informed me that it was a non-working number?

Called three times last night. 4:50, 5:49, 8:20
Didn't pick up and left no message.
