It sad that you made that losses but we the bitcointalk community could not help i your situation but only to discuss matter with you and get the attention of the forum representative for Betcoin.ag for you to resolve your issues or discuss with. In my part, I do believe that there is just a miscommunication between both parties and that could be resolved. If not then I guess you need to move o  OP and find a better platform instead. Do not forget to read the Terms and Agreement of the platform you will be joining.
