Not a scam as such, but
Last thursday the combank app on my phone alerted me to a $5 transaction on my credit card to the smith family in Sydney, so whilst I'm looking up what it is the app tells me that I've just spent $399 at David Jones in Sydney umm nope not me so hit the block card function on the app straight away.
Ring combank and explain that the $5 and $399 are not me, and that they need to cancel the card straight away, guy at the other end of the phone is great and does what needs to be done, whilst talking to him he asks " did you just use your card for Myers online?" umm No and then he says "well I'm guessing you haven't just tried to set up a new paypal either then" um no
Anyway I made a note of the transaction numbers as they showed on the app and after a phone call to Myers and David Jones I now know what the gifts I bought myself are and where they are getting delivered!!
