got a few missed calls from this number as well. i called the number back and its a research study on behalf of usc and ucla. if you give them your number they will remove you from their call list.

so it was legitimately a survey thing? they answered when you called back?

because i actually answered the call and answered all their survey questions and im wondering if that was a bad thing to do....

Depends on what they asked. It's not necessarily a bad thing to do but why do it? I can see nothing but downside. The survey might have been for real but might have been a scammer. You're under no obligation to answer the survey. Just tell them to put you on their DoNotCall list.

I've received 13 phone calls.  As I do not know this number, I never answer and wish they would stop calling.  Thank you.

New number, called hung up when machine came on.
