    Pool at Madison Riverside CA was too dirty to swim in this morning. When I complained, I was told there were no complaint forms but I could call the sales manager when he came in around noon. The staff member Christian was very polite and professional.

    I’m a member of the 24 hr gym in Valley Stream NY ever since that gym opened. Is it pools rules to allow members to Video tape in the pool area and inside the pool? I find that invading my privacy and others while we are in our bathing suits. In these times of social media, I do not want to be trending on anyone’s social media account. I’m very upset about this.

    My 24 Hour Fitness App is limiting, Blocking access to On Demand Work out Feature for the past 2 weeks, prompting me to “Upgrade” my Membership. I do not wish to upgrade my Membership, and would suggest blocking access to All App features unless I upgrade is an Illegal practice. I request full access to my 24 Hour App features. Member ID # BLC29004606. Please contact me at 347-993-5763 before I refer to criminal complaint and attorney general follow up for Consumer Fraud.

    At what point does the Yorktown ,NY location open back up to 24 hours? And at what point do they install the pool here? Also when do they start cleaning the mens room. As a whole the bathroom smells like dirty feet, ass, and piss.
