Who called from 4028299110

Got a call.  Left no message.

Called 6:21 EST. No message, came up unknown on cell.

Got several calls from this number; left no message. I don't know anyone in Nebraska; figured it was a telemarketer.
Decided to have some fun with it: answered the phone "what?" The caller hesitated; I repeated "what?". Caller: "never mind, we'll call you later". Somehow, I don't believe he will. Fun!

Have received a call from this number once for the past few days. Never answered, have not received any voicemails.

Have received several calls almost daily. No message left.
