They won't pay you $45k because they won't say they're responsible. It's true they could've stopped you because they knew your ip address. If you'd won they wouldn't pay because you had many accounts so they're responsible but won't help you.
It's a sad story. You've created accounts to gamble & lost $45k which didn't belong to you. Why did you keep $45k money which belonged to other ppl ?
Yes , the fault is all mine . I shouldn’t keep these money.
I thought that with a few high spins may win some money and be able to keep them but after loosing and trying to recover the losses things go worst of-course
