Received form Lovelace two mysterious and urgent "...

Received form Lovelace two mysterious and urgent "robocalls" in two days directing me to urgently make an appointment. No word about with whom or why. Three return phone calls met with no understanding, but "we'll call you back." Now, it's 6:00 pm, five hours later, and I'm told there is no one answering their phones except someone, "Jeff" who just happened to be walking by when the phone rang. I'm further told I could call the emergency room, but that even then, I would just talk to a robot, since it is after hours. I'm worried.
