I Lost on Betnano Casio Account Suddenly

I had ₺900 in my Betnano Casio account, but suddenly almost all of it disappeared, leaving me with only 74 kuruş. I have no idea where the money went, and I never made any withdrawals or transactions that could explain this loss. This is incredibly frustrating and worrying. I’m urgently asking Betnano to investigate and help me recover my missing ₺900. Is there a contact number or a proper way to file a complaint? I want clear communication and a solution immediately. Losing this amount without explanation is unacceptable. Please, Betnano, take responsibility and fix this problem quickly.
