Tried calling back but its always forwarded to an audix voiemail.

Same here.  Possibly a scam?

Same here, went right to Audix.  Tried calling back a dozen times.

Call was from an April.  Just to call her back.  She did not say what it was about. I did nor call back.

Received a call from this number.  She left a voice mail.  "This is April with Wells Fargo.  I *need* you to call me back today at 480-375-9003."   Called back twice and it went straight to voice mail.  

My accounts are in good standing so I can't imagine why I *need* to call back.  Hope it's not some sort of scam.
