Some type of scam about rewards for loans.

I just got a call from them, but they hung up after 3 rings before I could answer.  This is the second call from them in a month.  No idea who they are or what they want.

This 319-214-7300 number was on my cell phone.  I was gone at time the call was received.  First time have received it.  Glad to know it is a scam.  Therefore, will on high alert!!
