Bad service

My name and surname is Hopewell Mzu Manyamalala, On 06-02-2021 I was at the gym (Zonefitness Phillipi) and discovered that the water was not available, and no signs at the entrance. I asked for an manager's email address and receptionist gave. (To Cut story short) At the changing room one stuff member pushed me saying that I left papers under the branch, i pushed the guy back. The gentleman who were there at the changing room stopped that. Only to find out that this guy is drunk at his duties. Same stuff member pushed me again outside the changing room, I pushed him back too. I wrote an email that was expressing my treatment at the gym that day. In less than 3 hours manager responded and he sent an apology about the service and he said i need to name the person who gave me a bad treatment. It was impossible for me because i did not know his name and he had no nametag. The branch called me saying that they need to know what happened, only to find out that they discontinued my membership. When i asked for a reason, they said i violated the gym rules but the same manager said he is apologizing for what happened but now they make this as i am the one who caused this problem. He **** to me first saying that his employee is fired already but he also said he is waiting for DC and labour department to conclude the decision.

I need an a decent apology from the manager including the management and return my membership. Please investigate for me. Mzu
