Hi, I recently tried to buy a car of the website gumtree. I met with the owner and test drove the car, then decided I'll buy the car for $6000. I payed $3000 deposit internet transfer to owner. One week later, I returned as agreed to finalise the purchase, but instead got bad news from the owner saying he had changed he's mind and did not want to sell the car anymore. So I asked for my $3000 deposit back and in reply was told no from the owner and there's nothing I can do legally to get my deposit back? Do I have anyway legally to get my money back under Australian Consumer Law?
