Hi, I've sold a product on gumtree and I have one person who has bought a few of them. The last time I sold one she was claiming it was not enough and the wrong colour, which I believe it's not. This person has also made up lies so many times when buying from me, but she has returned the item and is saying she wants a refund. I have not said I will give her a refund because I do not trust her and think she has just changed her mind, but she is threatening me with a police report. The product was only $300. Can she take legal actions against me or file a police report under Australian Consumer Law?
