After the founding members of the gym applied for the card, they haven't opened for half a year and can't get it back. How can we complain?
This kind of matter belongs to the industrial and commercial bureau. You can complain to the Consumer Association of the Industrial and Commercial Bureau, because this kind of thing is the infringement of the legitimate rights and interests of consumers by enterprises. Don't say complaining is useless just because you haven't complained yet. You won't know whether it is useful or not until you complain. Let the industrial and commercial bureau safeguard your legitimate rights and interests, and let the industrial and commercial bureau chase the gym to give you a refund.
