Their username is Ymkshenron.
I am attaching screenshots of our conversation. He doesn't explicitly say that he will return it in these screenshots (he did later but I forgot to take a pic and closed the window) but he apologises and agrees to getting in touch to resolve this. I understand if this is not enough as it is somewhat vague, if that is the case then I will message him later and provide screenshots in another reply. Btw sorry for the profanity I used, got kinda surprised/shocked by my own stupidity.
