called back this number after numerous missed calls, was put through to an automated service that knew my name, however, required me to enter date of birth and "other details", hung up before it would go any further. The voice message stated at first "this is an important message for You, this is not a marketing call"

Awaiting confirmation from the bank, however, I find it suspicious that the bank would call and make me enter personal details before I knew who or what I was speaking to

I called back number (02) 6181 1094 reached voice mail for a company called Commonwealth Bank.
