Crunch Fitness review: membership

I signed up for one of those promos they had going on but less than a day after I did, I received notice that I'm moving so I tried to cancel. Ive never been to the gym, never activated anything, never picked up barcode scanner and new welcome package, never got into touch with one except the managers at the store locations and they told me that it's absolutely nothing that can be done to break a contract, they have no loophole at all except to pay for something you're not attending monthly for 90 days then after you're up to date on your payments you can cancel in writing. I been trying to contact management since 5/12/19. They only information they have is my card number, no ACH information.! I've never heard of such membership agreement ever. Is this even legal? Please help.
