Business ProfileforYogaSix Midtown

On 1/3 I tried a "one month of unlimited yoga for $23" offer at YogaSix in midtown. There was a contract that they did not talk me through, and they required that I sign at the bottom to attend my first class. I saw a charge of $136 on my credit card on 1/23, so I called and emailed asking that any ongoing membership be cancelled. In reading the contract I signed, it says that if my initial term is one month or less (which it was), I must give at least 30 days written notice of cancellation. I signed the contract on 1/3 and my membership began on that date, and the reoccurring charge of $136 happened on 1/23 (20 days later). That was charged within 30 days, so I still should have had 10 additional days to let them know that I did not want to continue with a membership. I let them know via phone and email on 1/23 that I wanted to cancel, and again on 1/25. The first response I received was today (2/2), stating that "Because that intro deal is attached to a month of classes, I will not be able to refund the one month payment from 1/23." It seems exploitive to allow a charge of $136 to go through on 1/23 when I requested that it be cancelled on the same day (inside the 30 day window). Or if they really are unable to edit their system in any way to STOP an exploitive charge or issue a refund, they could have at least altered the month of classes to which the intro deal was attached to be 4 or 8 classes. It seems unlikely that their system really cannot ever issue a refund. I tried to contact ************ times (by email and phone on 1/23 and by email and phone on 1/25). I would like them to abide by their contract and honor my request to cancel any membership that was created by trying the one month of unlimited yoga for $23.
