Called my mobile but I didn't answer and they didn't leave a message so i don't think it was important. Could be scam?

Allianz Insurance: Returning my call

Genuine call

Woman who called claimed she was enquiry about my CTP greenslip, saying my details were sent to someone else. When I questioned her for the registration number of the vehicle she claimed she could not give me that information due to privacy reasons. Told her she was probably a scammer, and if she wasnt please email the details to me. No email has been received.
