It's better to move this in the scam section there are additional good investigators there that can trace who is telling the truth, the weight is on Trubet because OP is denied payment for something he worked on, Tru bet must provide valid proof that OP has multiple accounts, there are no parameters here where users can get a warning if he is having multiple accounts before he can play, this is what happens if you are offering a bonus, without parameters implemented for double or multiple claims.
