Caller: Do not call register

This number came up on my caller ID - it was a lady stating she is from the 'Do not call register' etc, I got transferred to the authorization manager 'Brad Williams' because I would not give out my DOB. Brad asked for Credit Card details and went through the history of my telephone payments (with Telstra) stating I have always paid on time etc. because of this I can go on the Do not call registery. (I am not with Telstra). Once I told him that I will not give my DOB and Credit Card details over the phone he hang up,

Somebody claiming they are from a phone call scamming company and we have received a high volume of calls. Yeah a high volumes of calls from your scamming party.
