It's very difficult for the members of this forum to help you because you don't want to provide any proof, so you created this thread:
I'm not saying that I believe OP's story, at the same time am not siding with the casino, but in such cases, it's really difficult for the accuser (OP in this case) to prove his innocence. What kind of proofs do you think he can provide to support his case? How can he prove he doesn't have any alt accounts?
In such cases, the best thing to do is to refer to an independent mediator such as casinoguru or askgamblers then each party can submit their proofs and tell their side of the story. yep, I agree, it would be the best course of action. a user and I suggested that he post his complaint on askgambler and casino.guru, OP did
post a complaint on casino.guru and has talked with people there helping him resolve the issue and is now waiting for the casino to reply, as for askgambler, not sure if he has posted there yet since the most recent complaint that was posted against blizz.io was last april.
