Rang wireline. Left no message.

Called and left no message.

No message left.

Unknown caller to one of our cellphones.  If these are the google-scam people, they had also called our landline a few days ago [I don't recall the caller number].

Called my cell and left no message.  I recently launched my business website and have been inundated with these stupid calls.
When I started my business I also went to a search engine optimization workshop where I learned some great things.  The one thing that stuck most was the fact that Google DOES NOT CALL people.  They don't need to because they already know where your site ranks.  If you want to pay for an ad listing at the top, you call them.

So I don't know who called, but since others got a call from them, I will watch for the number in the future.  This is my business phone and don't want to accidentally block potential customers.
