I called back number (08) 6244 2702 reached IVR of company called ANZ insurance department.

ANZ bank insurance line. They will harass you for weeks if you don't answer and tell them to bugger off. Even then they'll call back 3 months later for more of the same. Pains in the arse.

Its the anz bank. They send you info out about anz insurance then spend weeks trying to call you to see if you got the info and want to buy their insurance. Once I said no and the person got really angry and pushy.
