Scammed by a buyer. Help Needed!

Edit: Thankyou so much guys, he gave the money. Grateful to all of you. ❤️

So a buyer scammed me by not paying for the tick*ts. First of all he said to pay after delivery which I agreed but then he kept making excuses and said to pay after concert just in case they won't allow him to enter. Now he is refusing to pay for them.

I know this sub hates scalpers but I was literally giving them at cost. It breaks my heart to see how can someone enjoy the concert knowing that they looted an innocent being. I don't know how to proceed regarding this and am very tensed.

I can show screenshots of chats if anyone needs them.
