the message said it was a correctional facitly (not actually named) and gave some official sounding message about scams with call forwarding and then said press 0 to accept the call.

they called several times early on a saturday morning, before 8am.  when we answered a man was on the other end of the line and said that if we accepted the call in error that we could call another number and get a refund.  When my husband declined to write the number down the man said "well F you" and hung up.

didn't answer,,, no message
