they call me everyday leave no message and i dont know who it is.

I recieved a call from this number today and It jsut hang up in my ear.I have no clue where (0398) are's code is, but this number is very weird..

Called me today, missed it, didnt leave any message.

rang me today asking questions about my telstra phone service however didnt sound very professional, sounded more like a prank call from a ditzy girl.

Missed call on my mobile from this number - no message.  Interesting, call was to my "private" mobile, which only 1 other person has (and it wasn't them :-)...

rang phone number back from landline and got a recording thanking for my interest and that I had been called regarding missing a call about their products and services. sounds dodgy. would imagine telstra would have a private caller ID on these numbers. anyways rang from work so if its one of those calls that costs an arm and a leg, work got it!
