The gym leaked the mobile phone number of a female customer and was harassed by a male customer

For this male customer’s harassment, you can call the police, and the public security organs will impose warnings, fines, detention and other penalties. You can also ask him how he obtained your number, and then follow the clues to find the person who leaked your number.

If your number is indeed leaked by a gym employee, then this kind of leaking customer information is a violation of the service contract and an invasion of personal privacy. You can ask the gym to compensate for the loss. Apologize and eliminate the impact. If the gym refuses your request, you can file a lawsuit on the grounds of breach of contract or invasion of personal privacy, requiring the gym to compensate for losses, apologize, and eliminate the impact.
