I had this happen with my credit card - out on a shopping spree and got a text message blandly announcing my credit card was blocked (no contact number to ring back, no name of the bank !!!). I got home and rang the bank for the credit card I had been using - was it the $600 tv I had just bought? or the $300 of assorted homewares? the GPS navigator? No - it was the $6 EBay purchase I had done the day before. It was a "foreign transaction" and not an Australian thief buying TVs etc that really got them wound up. I then had to ring all the stores to check that my credit card payment did actually go through and provided them with my phone details so they could ring me if there was a problem. The following day this happened to another friend of mine - a very senior government official (same bank). He was also not amused
I wouldn't mind if they had rung to check, but just cutting off a card while I was out? And no number to ring? Crappy service!
