Thx so much! Your answer will be definitely a help. I have provided everything needed for the shoes. And just contacted the buyer, the buyer said his/her friend found it not authentic without any photos or other stronger evidence. But I have everything, that makes me feel confused. Might think he might be scammer or misuse of return. I will talk to eBay CS tmr. Thx mate, thx so much! You helped me a lot! Good night and stay safe!
