Received text from 0439 208 230 that credit card had been used - 4 times illegal transactions. When I replied 'no' to approval for the entries, got a mobile phone call almost instantly requesting I call the 1300 360 252 number or hit any key. I did not. I jumped online and contacted the credit card company via the phone number online. The online number for contact was similar but not the same. Also checked my statement online at the same time. There were 4 illegal entries. Card blocked immediately.
