Same as bunny. I missed the call, and then returned it a half hour later. It was automated message saying my number would be removed from their "do not call" list.

I answered a call from this number.  They never said anything and hung up on me.

A couple of comments here say that if you call back you get an automated message saying your number would be removed from their call list.  So, the only calls they are expecting at their business are calls of *protest*!?  It's like they're admitting they are up to no good and they're expecting to be pissing people off!  That's definitely not part of a good business plan!

We didn't answer their call.  CallerID shows 'Atlanta GA' - a local area code to us.  From the comments, it sounds like they're trying to sell a 'service' related to increasing the web presence of your business website in online searches.

Since this offer comes in on a telephone call, we automatically consider it to be bogus.  It is against our policy to do business with, or share any information with, anyone who wants to initiate something in a phone call.

hung up when I answered

I'm pretty sure this the real Google wanting business owners to update their addresses.
