After years of using Trade Me with no issues, the last trade was fraudulent and the police said this was not unusual.
I went to Trademe, the police, and bank as they suggested and the result... Trademe, the police and the bank all say they can do nothing.
Apparently the Trademe account was taken over, the email account was taken over and the bank account was taken over and the money was sent from the receiving ANZ account overseas within minutes of it landing and withdrawn there in hours (from what Kiwibank advised in their recovery attempt).
