My daughter shruti ranjan was the student of 1st yr. 2018 batch in dayanand sagar college of architecture with vtu usn no. 1dc18at076. She was given admission in management quota after giving donation of 4 lax and complete one year fees of rs. 4.65 lac.
She is not continuing in this college as her health was not permitting. This year she is going to join in other college hence we demanded her original certificate back which was submitted to the institute during her admission, but the secretary of the college is denying and demanding 15 lac rupees to do so. This is against ruling laid by aicte. Please help me in getting the documents back.
