Call came in with no message left in voice mail. I know no one in Oklahoma. It came in on my business cellphone so I am going to assume that it is a Google reseller and website developer. These are scams. Their pitch is to help your rankings on google which I don't need since I am on page one under my industry in my area.  Do not and I repeat do not do business with anyone that calls you on the phone. If you need a website get it local. Never, never do business with anyone who calls you on your phone. Keep your business local so you can do business face-to-face.
YOU HAVE BEEN WARNED!
