Denial of tc

Hi, I'm Deepa. My daughter studied in Vibgyorhigh, balewadi, pune. I had to change the school as I shifted my house. During the summer vacation I was in Chennai and went to few more places to visit my family and relatives. At some places I had network issues and was unable to receive the mail sent by the school. It stated that I need to pay the annual and first term fees or I need to inform them about TC. As soon as I was back that is 2 or 3 days after the school reopened , I went and requested for TC. They denied to give it and told me about the mail. I have received it only a day before. I informed them and explained everything but they kept on saying that it was the policy and rule followed by the school and I have to pay the amount (Rs 45000) approximately otherwise they will not give the TC. They did not allow me to meet the principal either. Wt should be done? Such rules will hinder the education of kids. They even added that some people have paid them and then got TC. How are they allowed to do such things?
