A scam I haven't heard before - call on my mobile when answered is a verbal message telling me that there are two unusual transactions on my Visa cards. One supposedly in Australia for $400 and the other internationally using a card for $1100 and inviting me to press 1 to confirm they are correct or 2 disputing them or 3 confirm my address. Hung up without doing any of those tempting actions and checked my vise card accounts - no such emergencies. the number called from was 0411 536 645
