Automated message telling me to call this number.

just telling me to call that number back,

message telling me to call the number.  It's junk calls and I don't respond to those

Called twice back to back.  I do not answer my phone when I do not recognize the number.  They left half of a robo message to call back.  I didn't.  If this were really a company such as a credit card company the I had a card with, they would have left a legitimate message.

Keep calling and hanging up
