I've been getting these calls stating I am being investigated for fraud. They provide a reference number.  Be careful. They are calling from other numbers too: 214 716-0407, and 214 272 2394.  The  message sounded fishy, so I never picked up.  When I got the first call, I did research on the net to find nothing which speaks volumes. I have never called back, but they keep calling. They even called at 6:30 in the morning.  I'm going to provide this info to the local law enforcement.

Check out the comments from 214-716-0407. http://800notes.com/Phone.aspx/1-214-716-0407#p637611455107285888
They will become angry and abusive on the phone trying to collect money from you.
