Seeking knowledgeable experts to come and take a look!!!

The reason for this is that I spent 3000u to join a certain master's quarterly membership in the square, but within a month of following the master, I lost a significant amount of money, and now I can't contact the master. How should I handle this situation? If I report it to the police, can I recover my lost u? I accept the losses from following the master, but after paying for a quarterly membership, the master disappeared in just one month. Can I recover this 3000u?
