I got an email from my parents saying that my bank had sent my account activation details to Australia.

More madness!

What would have happened if I had been renting in Australia or had sold my house? What if there was no one to intercept my misdirected mail?

I went to the bank to alert them of this stupidity. They apologised, saying that someone had accidentally switched around my current and previous addresses. I am skeptical, though. Somebody told me the same thing had happened to them. I think there may be a systemic fault here.
