Do you want to know who is using the Robo Dialer to call your cell phone number. It is Marriott. Never stay at a Marriott Hotel. Say NO to these idiots who think robo dialers are a productive way of getting the word out about their promotions. Record the calls on your cell phone. Take a screen shot of the call log.... file a law suit worth $1500 per incident in court and fight back. Fed Up? I am. That is what I did. I won the lawsuit. Take the individual hotel in your area to court - you will win. Teach Bill Marriott a lesson.
