Im getting missed calls to my mobile from this number and no message is being left. Im nearly getting them everyday - but they ring while Im at work and out of range.

They rang and hung up when I answered

It's from Commonwealth Bank (or someone working for them), trying to sell accident insurance.

have had 3 calls already, hung up as soon as I took the call.Who does this sort of stuff?

Hi we've been harassed by this number for several months receiving calls for someone who does not exist, at least 4x a week.  When you call this number after hours (after 8.30pm) you get a message indicating that it is Direct Call Centre calling to sell insurance on behalf of GIO and Suncorp...in the message there is a 1800 number to call to organise removal from their calling lists. (sorry I don't have it on me) if you call duiring work hours you will be sent to an answering machine and they don't return the call.

I have had several calls from this number and they do not speak..?

I just got a call from this number. They didn't leave a message.

have had 3 calls already, hung up as soon as I took the call.
