Where should I complaint this via online

Headmaster's Name: Gandhi School Name: Government Hr Sec School, Mullai Nagar. School Address: Mullai Nagar, Hosur. City, State, Zip Code: Hosur, Tamilnadu, 635109 Dear Sir, I am writing to bring to your attention some concerns regarding the conduct and treatment of trainees under the headmaster's supervision at Government Hr Sec School, Mullai Nagar, Hosur. I have observed a consistent pattern of rudeness, mistreatment, and inappropriate demands that have raised serious concerns among the trainees. Firstly, there is a prevalent issue of verbal mistreatment where trainees are subjected to harsh words and disrespectful language. Such behavior not only undermines the learning environment but also fosters a negative atmosphere, hindering the overall growth and development of the trainees. Additionally, it has come to my attention that trainees are being pressured to contribute financially to the school after completing their training period. This practice appears unprofessional and contradicts the principles of a fair and equitable educational institution. Education should be a pursuit of knowledge and skill development, not a financial burden imposed on the trainees. Furthermore, the mandated working hours of 8:30 am to 4:30 pm, coupled with the considerable travel distances some trainees endure, pose a significant challenge. This stringent schedule may adversely affect the well-being and overall performance of the trainees, potentially compromising the quality of education they receive. Moreover, the lack of respect and understanding displayed by him towards the trainees is disheartening. As a headmaster, one is expected to serve as a role model, fostering an environment of mutual respect and support. The trainees should feel valued and motivated, not treated as mere servants. I urge you to address these concerns promptly and take appropriate measures to rectify the situation. A positive and respectful learning environment is crucial for the success of both the trainees and the institution as a whole. I believe that with your intervention, we can create an atmosphere that encourages growth, respect, and a commitment to excellence. Thank you for your attention to this matter. I look forward to seeing improvements in the near future. Sincerely.......
