A local car dealership asked for $1000 deposit to secure a vehicle that we were interested in purchasing based on having a test drive first. The vehicle was not yet in stock and needed to be delivered. Upon test driving the vehicle we decided it wasn't for us and asked for our money back. The only documents the car yard have are emails, we did not sign any paper work. Now the owner of the car yard is saying that we are not entitled to our refund... Is this legal under Australian Consumer Law?
