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.

Who is this?

Please stop calling me.ot interested in your offers.

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