Called but left no message. Received another message yesterday from 313-545-0139.  Had received earlier calls last Friday from the same Caller ID, but from numbers 313-338-1067, 313-545-0219 and 313-545-0228.  Per another post on 800notes.com, unlisted number 866-269-9419 may also be related, that number has also called 4 or 5 times in the last few days. They're approaching harassment now.
