Just got a call to y cell a few minutes ago. No message.

Our landline number got this call too especially @ 9:35 this morning.  It is a telephone scammer claiming to be part of a customer survey.  Their machines are doing all the talking and never gives a real person!  If anyone else has any addtional information on this, their call back number is 1-800-756-6168 and ask for their security team if worse comes to worse!
