It is an automated service calling on behalf of Creers Australia about getting you to enroll in a course about Telemarketing and Call Centre Operations. I have blocked their number on my phone.

Rang me but was busy so couldn't answer looks like a good thing I didn't have time to

rings 3 times and hangs up... grrrr...

Annoying pests, ring and when you answer they hang up

Same here. Not listed, keep calling, no V-Mail. Probably some robot dialing to see if this is a real number.

Calls a couple of times a day. When you answer they hang up. Very annoying.

This rang and left no message. I called back and received a recorded message: "You have been contacted by Careers Australia [something about marketing] about career opportunities..." I hung up there.

ditto situ to Steve - no message left

this number is not listed but they keep ringing me and then don't say anything???
