Right as cold/flu season was taking off, the location near me went and removed over half of the equipment cleaning stations (paper towel dispensers & spray bottles), so I decided to cancel my membership. After hearing so many horror stores like yours, I was shocked at how easy it was, since I was able to cancel mine online.
Although, I did quickly learn that I had also effectively prepaid for another 3 months, so even though I cancelled on October 31st, and was not charged for anything after that date, my access didn't end until January 31st. I think part of it was credits from the COVID times, but I never went back to test it, so if anyone reading this is thinking about cancelling, be aware that you may have access for quite some time after cancelling!
