Can't receive funds

"My name is Jethani Krutik Dharmeshbhai. When I was studying in Class 11, only ₹8,000 was deposited into my bank account by Diwali. Now, I have even completed my Class 12 Board exams, but the remaining installments for Class 11 have still not been credited, and I haven't received any amount for Class 12 yet. My classmates received ₹15,000 about two months ago, but I am still waiting for mine. I kindly request you to look into this matter and help me receive the pending amount as soon as possible."
