The delivery was delayed about 1-2 estimated days due to the auspost system. He threatened me to give negative feedback if not refund him, at the same time he requested not receiving and refund via eBay. I agreed to refund but in the next hour he received the parcel and never responded my message. He got my Lego with the trick and pay nothing.
I suspect he gave a fake address as the address he provided and the eBay id name is different from the id he used to chat with me.
