I put down a $200 deposit (by EFT) to hold some car panels for me from a Gumtree seller (we are both in NSW). He then sold them to someone else and when I complained, he said I was rude and refused to pay the money back to my account, and told me I would have to come and pick the money up (3-4 hours drive). He also told me that it was a business, but when I left a negative comment about the business online, he then said it was a private sale, and because of my negative comment I would never get my money back. I have the entire discussion back and forward by text. I just want my money back. Is there a gumtree refund policy under Australian Consumer Law?
