I am not siding with metaspin or you and I'm sorry and no offense but did you read the complaint you shared? the verdict of the complaint was unjustified because casino.guru found the evidence given by metaspin that the complainant broke the casino's terms and conditions to be sufficient. in short casino.guru finds the action metaspin made to be justified based on the evidence they shared with the casino.guru staff.
casino guru works on the casino side. this is already clear to anyone who watches how they handle complaints. Here money is stolen from a person on the grounds that he has other accounts. But at least some logic, why does he need these accounts if he makes a deposit without using bonuses?
