Called but left no message and I do not recognize this number. Any business  or person of importance would have left a message.  Most likely a scammer.

called back twice, nothing but busy.....probably a spoofed #

Just called.  I waited before responding, maybe 6 seconds or so, then said Hello, Baltimore, Michigan!  Still and open line.  No hang up.  Hit and pressed # for about 15 seconds and then hung up.  We'll see when/if they call back.  (and as an aside 800notes is the best for these number look-ups)
