Con artist scam

I also have been getting calls from similar prefix numbers 0488 815 670
0488 815 669 0488 815 386
they answer and know my name but nothing else. The person claims they are making sure my super has not been affected by the recent changes. When asked they cannot give me a company name only that they are a private company.

I rang back the number 0488 815 583, spoke with someone who hung up right away
