After booking a room from a rental website (cushybnb.com), I made a money transfer to the “owner” of the place into an account with the Commonwealth Bank of Australia. Very soon, after reading posts on TripAdvisor and other sites, I found out that I had fallen victim to a scam. I tried to stop the transaction being completed, but the Commonwealth Bank of Australia answered that “unfortunately CBA is not in a position to assist you”, and recommended me to contact the “Financial Ombudsman Service” (no help there either). In other words, mind my own business, not theirs.
Don’t think wishfully: Once you fall victim to a scam in which a bank is involved and should be accountable, you are on your own. Banks like the Commonwealth Bank of Australia will side with their customers. Never mind those customers are fraudsters. They don’t care.
