Cancelled Credit Cards!!

Look at me, writing two days in a row! Anyway, can I just say how annoying the bank has been since traveling?? I informed them before I left and once I got here that I will be in Australia yet they still continue to freeze my debit and credit cards when I make "unusual" purchases. It's happened multiple times and I fear it might have just happened again. Jojo and I are booking flights for our post studies travels and first my card was declined so I had to try a different one and then when we were booking a second flight hers was declined but mine somehow went through! UGH, the things I have to put up with. :)
