Trang Vo-24 Hour Fitness-1700022918

I would like to file a complaint to 24 hour fitness in San Jose locate to Eastridge loop. I don't know what I did, the manager at the site don't let me in. Today, he didn't let me in the fitness, I asked him what is the reasons? He responded he doesn't like me and don't want me to work out at that site. I tried to recalled of what I been done wrong but nothing pop up. He treated elderly person with unrespectful and racist. This is unreasonable. I want to bring this up to stop this happening to other elderly person. I paid for to use the fitness what right did he has for not letting me work out where I want to go? I want the explaination, is this how 24 hours fitness treat their customer?
