Didn't answer, had do not disturb feature on, so did not hear the phone ring nor did they leave any message. However incoming calls are listed on my log and this one came in at 9:23AM 8/19/2016. It is a totally unknown number to be so it MUST be SPAM or a SCAM. BLOCKED!!! Maybe some day these a*****oles will get the message and stop. Meanwhile I'll use all the countermeasures I can, including reporting these to the FTC and posting them on 800Notes. (THANK GOD FOR THE DO NOT DISTURB FEATURE ON MY PHONE SERVICE!!!)
