As per our internal procedures and findings, your account was confirmed to participate in a multi-accounting and bonus abuse, which has triggered all relevant sets of procedures.
Unfortunately, due to all the gathered evidence, your accounts were disabled and fraudulent winnings were removed.
If in the future there will be more accounts created on your behalf they will be disabled upon earliest detection.
Instead of just saying the OP has multiple accounts at your casino then I think you should also be transparent about your findings including proving how many accounts are registered to his name. This case doesn't have to be resolved unilaterally like this because the OP looks very confident and continues to defend himself because he doesn't register more than one account.
Your response is positive, but I don't think it solves the problem. There are question marks, and you have to be able to prove those findings as well so that everything is clear and we know who is to blame.
