Missed call from this number left message claiming to be from Commonwealth Bank, when i tried to return call it showed as "call failed".

Caller hung on answer. Tried ringing straight back, wouldn’t even ring.

Phone blocked it as Suspected Spam. Called the number back from a land-line, call couldn't be put through.

Caller hung up on answer. These are frustrating in the extreme. The Telco industry needs to work out how to stop these calls. But then again, the industry gets some revenue from these things, so maybe it is not in their interest.
