Caller: something to do with superannuation

It was very suspicious. She knew my name but nothing else. I told her unless she could prove who she was representing, I wasn't giving her any personal information. She asked if I had received an email recently regarding my superannuation. I asked her if she knew my email and she said no. I told her I wasn't telling her anything and I hung up. Sounded like a scam.

Fakey fake.
Pretending to be checking "defunct superannuation accounts" that the government will be targeting for closure.
Personal details probably sold from another scam company I got rid of the other day.
