travel scam  to the US Airlines you've won air place tickets

Picked up and no one was on the other end.

I didnt pick up cause I dont pick up unknown numbers but no voice mail was left. and i texted the number to see who it was and it said it was a disconnected number

I don't pickup this number because I was busy at that time, I call back but no one answer.

I got a completely different message when I called back.  It said this was an "opt out" number for "Electrical Services." Since I was born at night, but not last night, I hung up.
