*************The old Google Placement Scam***************
Called yesterday  - did not answer -  no message left - have blocked their future calls.  

Buy a call blocking phone or device.  They work and they are inexpensive.

Google ad placement company.
Asked for the boss buy first name.
I asked the telemarketer what he wanted instead of answering the question the hung up.

I get a call at least 2 - 3 times a month, maybe more.

2ND call in three days, in each call they ask for the owner by name and say he is expecting their call.  They are returning his call.  this last one said it concerned pre-litigation concerns.  Hung up when I put them on hold.
