This was a serious Westpac Bank Scam. The man posed as someone from Westpac and told me I had unusual credit card transactions on my account totalling over $1000. He had my name, phone number and the last four numbers of my credit card. He kept me on the phone for over 20 minutes while I went through my account to see if there were any unusual transactions (there were 2 for $30 each) . He then tried to get my customer number & other identifying details via the keypad on my phone. . I refused & hung up. He rang back a second time and I hung up. I called the bank directly & they had no record of any call being made by anyone from Westpac. Westpac cancelled the card.
