Who called from 4028350023

Caller hung up not leaving message on answering machine. Call comes from Columbus, NE.

I know no one there or have any business dealings with any company there.

I said Hello twice, and there was a recording that said "GOOD BYE" and hung up. I tried to call back and it went straight to "The person you are trying to call is not available, please leave a message."

I have gotten the call 3 times in the last two days. Same thing everytime,you say Hello and nothing and then a automated womans voice say good-bye. Tried calling back and it said to leave a message so I did a very angry one not sure if that was the right thing to do or not. What is this and where is it coming from and why me??

Did you leave a message?? I did and not a very nice one,not sure if that was the right thing to do or not??

A few calls received in the last few days.  No one says anything
