Local Lighthouse Google Optimization Scam - Say they work for Google!!!! Tustin CA

Received a call today that started out with a recording saying that they are calling from Google and have been trying to reach me about claiming my google information.  Kept listening to the recording because we've been working with Google to resolve some issues regarding our business address.  A woman came on the phone and said that they would be giving us 10 keywords and guaranteeing 1st page placement on Google, Yahoo and Bing for only $99/month. 

I asked where she was calling from because I was under the impression that it was Google and she said that, "yes, we work for Google and provide SEO for mom & pop businesses like yours to guarantee that your company will show up on the 1st page within 30-90 days of starting your membership with us...we also work on keeping you on the 1st page for the entirety of your membership with us." 

I asked her how they could do that when Google AdWords is much more expensive on a monthly basis and she explained that "because we are experts in what we do...it is all that we do and we are able to get you there."  She didn't answer my question, just says that they guarantee it.  She sent me an e-mail with a contract attached that had the breakdown in fees and also said she would send another e-mail with her contact information (I never received that e-mail).  This is a complete scam!!!  Beware!!!
