phone call from 1800 704 308. message was from male who said "um....hello" then nothing.  do now know number - do not want a call from this number - did not/will not return call as believe nuisance/scam/unwanted marketing or just plain crooks.

This number called me, i answered hello & after a few seconds a young lady responded goodbye. It sounded like a call centre in the backround.... I didnt call back incase this was some sort of scam...
