Poor customer service at its best and poor facilties

I have written too many emails to Virgin Acting Head Office, of which one of them was escalated to the branch concerned which is Amanzimtoti branch. Since I joined the gym in February this year I have complained in many avenues about their cold water in the ladies showers and no one is doing anything about it. I was once called by the manager by the name of Isabel after she had received my email via their Head office, who then promised to get back to me with this issue once she has managed to get the plumber on site and that was going to happen in May beginning but to date she has never kept her promise. I had even left a message for her at the reception two weeks ago but nothing. Virgin Active is expecting us to pay so much for membership but they cant even provide us with basics such as hot water to shower. I am very disappointed with the way they do not care of their customers. I have once caught flue due to having cold water in this cold weather as a results I do not go to the gym as much as I would like because of not being able to shower after gym so I can go to work thereafter. The way they handle our complaints as members is very disrespectful yet they know we have to pay membership fee without failor every month. it looks like they only care about making money and customer service and customer satisfactory does not exists. Seriously being told that the problem of cold water if a very long existing problem but nothing is done about it means what? If I do not get positive feedback here I will definitely take this further, I am sure there are many platforms out there to expose them from making money out of us by promising facilities that they don't have. I am not the only member with this complaint and I am sure we will raise this until we are heard or they must just cancel our membership without any costs hence they are failing us.
