Who called from 8139022347

They called my cell phone and when I picked up they didn't say anything then hung up.  CID says Tampa FL and when I called the number back I got a message that said the number was no longer in service.

I received two missed calls in a row from this number my cell phone.  One stated it was from Florida and the other said it was from Japan.

Some sort of scam.  You can't call back the number and even though it is a Tampa number someone from another country was on the line that sounded like a robot.

I received a call from this number and the caller ID says Japan? Tried calling back and the phone just hung up.

I RECEIVED A CALL THIS MORNING. I DON'T ANSWER UNKNOWN NUMBERS.
