Gym Charged Me After Cancellation - New York

EDIT: added more context below. Yeah i canceled my gym membership in May 2024 - sent certified letter, got confirmation, the whole deal. They still charged my card for June, July, AND August.

When I called they said their "system didn't process the cancellation correctly." Now they're saying I owe them for the months they charged because I "didn't dispute it fast enough."

This is Crunch Fitness in Brooklyn. I have the certified mail receipt showing they received my cancellation letter on May 10th. What are my options under New York law?

Total unauthorized charges: $89.97 ($29.99 x 3 months)

Adding my own story here because this thread saved me a lot of money. My gym in Jamaica, Queens charged me $450 in personal training fees AFTER I cancelled my membership. The kicker is I never signed up for personal training — they apparently added it to my account when I did a free trial session.

Here is exactly what I did, in order:

Key lesson: file complaints with BOTH the AG and DCWP. They are different agencies with different enforcement powers, and gyms in NYC know that multiple complaints trigger deeper scrutiny.
