Centerlink Scams

Hi Imperfect Mum can you please post.
Got a call from someone claiming to be from centerlink today telling me I have a debt with centerlink. Have never received anything in writing and upon doing some research have seen there was a similar scam a few years back. Please don't give them any card or account details! Luckily I didn't but don't want any other mums falling for this horrible scam.
Thanks xx
