Same number that rang 30 minutes ago, This time they claimed to be from NBN. Told them they were crooks and said to get off my line.

Thanked me for an ebay purchase, said that my 'account' had been charged $397. I the hung up. No purchase, of couse, nor do I pay for anything other than PayPal. Scam, designed to panic me and get some banking details I know.
