Called up their number, it's some insurance company cold calling.

It's Avon Insurance Direct. If you are a Commonwealth bank customer you will most likely get these calls.They have an auto-dialer that just calls as it's programmed to do.

This number calls me at least 4 times a day and then as soon as I answer they hang up -this is extremely annoying and they need to be made to stop doing this to people.

I also got a call from this number. They just hang up without speaking. Last week they were calling me from Sydney. I blocked that number. Now again from Melbourne.
