Same here, call at least once a day - no message left on voice mail.. I think it's just another number from the same outfit - some Google listing crap.
They call a couple of times in a row. Stated that my google listing says my business is closed. The thing is when you do give the time of day they are not from Google. They are a small advertising person, company trying to build you a website. Sometimes for outrageous amounts of money.
