Caller: mysterious company named "Impact"

I called back as could not find info. A lady with an Asian sounding accent answered (I'm so sorry for how that sounds, I just mean it sounded like a commonly experienced call centre), and would not tell me what the company did without verifying my mobile number (to "pull up my file"). Sounds awfully fishy to me if they won't even tell me what their company does without my details! I will block the number now.

Scam

I called back number 0420 988 779 spoke to a woman who said company name is Impact .
