Arbitrary Errors
I tried to add money to my AUD account. I transferred money from my NAB account. It took a very long time for anything to happen and then you said there was some kind of error like you got the money but couldn't prove it was from me, so your were going to refund it if I didn't press a button within two business days. This email arrived after business hours and I wasn't available to see it until two days later, so of course missed this arbitrary deadline. Then of course I wanted to call and find out was going on, but your phones are closed at 4PM! Then it took another business day for the money to be refunded so I could start all over again. Pretty frustrating.
