Hello mate ,
falcora finance website is falcorafinance.io if you want to contact them directly . If you’re looking to do chargebacks do not mention anything about gambling or they won’t accept , just say goods/services not received and then state you bought cryptocurrency or NFTs . But am sure falcora finance are done through APP payments which is a bank transfer so I don’t think you can chargeback those the same way .
hope this helps
