Taking into consideration what they've written about multiple accounts, I guess they're not planning to pay you. I don't know who's right and who's wrong here. Good luck to you and don't let roommates gamble from your computers again. Multiple-accounts are restricted in casinos as well as on bitcointalk. I'm sorry for such a big loss. Perhaps they'll pay you some part of money as a compensation but I'm not even sure about that. Good luck and take care.
