You can complain to the local industrial and commercial bureau if the gym closes down. If the local industrial and commercial bureau is not satisfied with the solution, it is recommended to sue in court. The services agreed between consumers and gyms are not special goods and services, and should follow the rule that "the operator shall bear the responsibility for replacement and return".
Moreover, because personal fitness involves personal rights, according to the nature of this kind of contract, it is not an enforceable contract. I hope that when you sign the agreement, you must clearly apply for membership cards or fitness services, and keep good evidence and agreements in case you need them when defending your rights.
Behavior of other complainants
Call the consumer hotline 123 15 to complain about rights protection. Some consumers impulsively recharged under the advocacy of merchants, and later found that their consumption was too high, or some promises of merchants were not fulfilled as agreed, leading to consumption disputes. Consumers are also reminded not to be confused by promotions such as long time limit and ultra-low price when recharging. Don't trust the verbal promises of merchants, sign a written contract and fully understand the relevant binding terms to avoid falling into the consumption trap.
