NO answer

received call from this number, when I answered no one on the other end.

"Frederick    MD"

Note all the spaces, and the lower case text

Seems Legit

Called many times. Used voice to call back. Rang and rang
no message no id
looked online for entity
Do not answer or bother to return call

Caller made 32 phone calls to my home between the hours of 8 AM and 5 PM today, and 24 times yesterday,  Thankfully my call blocker intercepts the call before it rings and gives them a polite message that I am not receiving calls.  Wish I could adjust the outgoing message to tell the nuisance caller what I really think about them.
