I am a personal trainer and a member consultant before. This is what it says when signing the membership application form normally. Once this card is sold, it will not be returned for personal reasons of Party B. ..

It doesn't matter whether you open the card or not, it depends on the reason why you return it. You say how to return the card, don't return it, even if you don't open it. But if you say that your gym is not good and how bad it is, it's almost noisy enough.

Pure hand tour, thank you for your adoption.
