I am writing to complain about the changing room in the sports center and its customer service. I often use this sports center. Reason I said that is, this sports center has swimming pools, football stadiums, gyms and many more. But the problem I am experiencing is the changing rooms ventilation system. You may think that it can not be that big problem, but after you trained for more than a hour or two, bodies temperature gets hot and as the result of that some kind of smells starts to come out from your body. Because of rooms air gets dirty fast staying in there for at least a minute is going to get impossible. Not only ventilation system, but also customer service is also unacceptable. Because I have complained about changing rooms for days and they did not respond to me once. Mistakes happens in our daily life but this one is kind of hard to accept. I would be thankful if you fix the problems that I wrote down. I look forward to receiving a resolution to my problem.
