Hang up call.  Not knowing the number, I didn't think it prudent to answer.

Called cell, no message

Called my cell phone and left no message.

The same as everyone else. :(

Same as other posts, one short ring, hung up.  I didn't call them back though, sometimes it's a scam that automatically puts a big charge on your phone bill.  I do business with walmart.com, so it could be legit, but as one poster wrote, they should deduct the $5 from the card!
