My brother had access to a couple of my online sportsbook accounts, and made huge deposits and lost it all. He obviously did not tell me, and I reported it fraud to my bank and credit cards. Being a US citizen, these sportsboooks are threatening to send this balance I "owe" them because the bank stopped payment to collections agencies. Does anyone have any experience with this? It honestly was not me, and the one book is working with me, the other not at all. Does anyone have any advice? Is this even legal since I'm a US resident, and they are breaking the law letting me gamble on their site anyway?
