Who called from 3015469237

Received call from this number.  Could hear the line was open but no answered me.  I hung up.

A simple trace shows the exchange 546 for Cumberland Md. but on another site the 546 exchange doesn't exist.
Got a call today at 3:09pm EDT. Came up as unknown but revealed the number. I let the answering machine get it.. no message left and hung up.. lol

After digging a bit more it looks like this number is a cell line with Metrocall as the carrier. What's interesting is when I call the number it says it's not in service.. lol

let go to voicemail. no message left

i got a call. Silent on the end.

Get calls from this number (301-546-9237) and they do not say anything.  It is very frustrating and disturbing.N
