New York Sports Club [NYSC] review: membership

In January of 2018 my daughter signed on for a "one month student membership" during her winter break. She canceled the same day she signed on as per the gym's policy since she was returning to college in a month. Gloria assured her that no further action was required. A cancellation number was not provided. NYSC continued to charged my daughter's bank card for February, March and April. Thankfully the bank resolved the issue. In May of 2018 NYSC began charging my credit card for my daughter's membership. Unacceptable and criminal. I've called and the 'gym manager' is never available to speak with. I've advised my credit card company that charges from NYSC are not authorized.
