I just got his as well!I called and it said goodbye and hung up!I had another one recently for some bogus quiz, the company was in Sth Australia.

Yeah, got the whole spiel about trivia line, but I've hanged up before getting anymore of the details. Hope they don't charge me. I'm calling my mobile provider now.

says 'goodbye' then hangs up.

Yeah same deal, looks like this company is scamming us with some stupid competition.

who called me

Just had a call from this number on a Telstra mobile phone - definately regarding trivia competition.
