Did not answer a call from this number.  They did not leave a message.  I do not answer calls from numbers I do not recognize and if the call is not important enough to leave a message, it's not important enough to return.  If it happens once, I assume it was a misdial.  If it happens more than once, I assume it's a scam or spam call and it is blocked.  Given that I've received spam calls in the past with caller ID saying Mt. Olive, NC, I'm going to assume they're at it again with a different number and block this number, too.
