Phone rang twice and I thought that was the end of it. Almost immediately phone rang again. Four rings this time but I did not answer hoping if it was a legitimate call the caller would leave a message on my answering machine. Did not leave message. This was at 4:23 a.m. per caller id. I was not a happy camper. Decided to "Google" this number to see if I could find out who called, to no avail.
