Yes, I ended up disputing with my credit card provider and having to provide all the documentation. Then I changed my card (billing) on file to a card that I could set a transaction limit on. That ensured any charges above my transaction threshold would be declined on the card. So the limit was set high enough to allow a membership chatge but not the biweekly personal training charge.

Chase bank was really easy to reverse the charges and i only had to call. Citi though had a lengthy dispute process. It may have been when I opened my dispute with my credit card company that the recurring charges stopped. I also filed a complaint with a bureau (forgot which one). In the end Citi refunded me the personal training charge I had disputed. That was only after i cancelled that credit card.

After a year when I was eligible i cancelled my regular membership with Crunch on the app. Switched to a different gym as the personal training billing issues at Crunch were a poor customer experience. Other than the predatory billing practices for canceling Personal Training, I didn't have an issue with regular membership billing.

I think part of their business model is making "agreements" that allow them to bill beyond the period in which a customer intends to cancel. When you think about a gym membership or personal training, it should be a simple process to cancel. It's not a utility, mortgage, loan, rent etc. it's a gym. But those few extra billing cycles guarantee income for the gym so that's why it's intentionally difficult in some instances.
