Who called from 3017763421

Says that I opted in for automated calls when there was an operating status change.  I do not remember doing this.  I believe that this is a Spam call.

Notification service from work.

It is a notification service. You probably signed up for it at work. It lets you know if there is a delay or cancellation at work.

It is probably Marty Randolph...

I must have been the call between both of yours this morning. My call came in at 4:16am.  All I have been able to figure out so far is the call originates in Laurel, MD.
