I've had calls on my home number (on Do Not Call list) and on my cell phone. Nuisance. I just hang up, and have not called the number back. I assume it's some kind of scam.

I am on the National 'Do Not Call' list, yet I am constantly called by this number.  I've repeatedly texted them to stop calling me.

I have had about 6 calls over the last 2 weeks.  All they do is call & will not leave a message.  I am on the Do Not Call List and they continue to call.

Calls every day and every night -- robocall leaves a voicemail that says: "A study is available at no cost and compensation up to $1000 may also be available. If you or a loved one are interested in learning more about this confidential opportunity, press one..." If you call the number back, their robo-operator says it is Acurian Health. I called them back-- but first blocked my own number -- to ask to be removed from their list. They keep you on hold for 23 minutes...then disconnected me. Awesome. Over the past two weeks, I've filed over a dozen complaints with the FCC about this number, as I am on the National 'Do Not Call List." I doubt they'll do anything about it but I am am going to continue filing complaints every time they call.
