I called back number (02) 8604 0050 spoke to a woman but did not say for what company.

Caller: credit corp

it's a credit corp number

I'm fairly sure this number is credit Corp a debt collection agency

I called this number back and they asked for my daughter Lisa, I asked who was calling and they replied that if they gave me the Company name they would be disclosing private information about my daughter, what a load of BS!, that's just taking the privacy act way too far, so I replied that I would not give a message to my daughter in that case and hung up!
