Fraud or scam: Money transfer, virtual currency, or money service

I was the victim of a ticket scam. I believed I was purchasing legitimate event tickets from an individual who represented that they would transfer the tickets to me after I sent payment. After I sent the money, the seller failed to deliver the tickets and refused to return my payment despite my repeated requests. The transaction was authorized by me because I genuinely believed I was paying for legitimate tickets. I did not realize I was being deceived until after the payment had been sent and the seller stopped cooperating. I have attempted to resolve the matter directly with the seller, but they have refused to issue a refund. I am disputing this transaction because I paid for goods that were never received. I have screenshots of our conversations and any other supporting documentation available to demonstrate that I was misled and that the promised tickets were never delivered. I respectfully request that this situation be reviewed as a scam involving undelivered goods and that my claim be considered based on the evidence provided.
