Got a call today, Sep.8, 2014 at 6:50PM PST didn't leave a message

Just had two calls from this number.  No message  

Call every night. No one on the other end and do not leave a message. Land line spam at it's finest!

Mountain West Research - they call every day, sometimes twice a day.  Unfortunately, the National Do Not Call List does not cover telephone surveyors, only telemarketers.  You have to contact them directly (email contact@mwrcenter.com) or register a complaint with the Better Business Bureau - I'm thinking the BBB complaint would be the more effective choice.

Received a total of 3 calls Sept 14.  I did not answer.  No messages left.  Appears to be coming from Roseville Mi.
