Osmania University — hike in condonation fees without any prior information before the beginning of semester

Address:

Osmania University, 500007

I am student o[censored]niversity college of engineering, our condonation fees till now was rs 1000/- as per the rule book (Pics i have uploaded), tomorrow is my external exam and today i found out my attendance to be 70% and i have to pay a fee of rs 2000/- all the students of b. E. Submitted a letter to principal that there should be a notice or circular passed before the semester starts about the condonation fees hike (Pic i have uploaded). But the pricipal says, "i will raise the fees as i wish, what will you do". These are the exact words said by the principal o[censored]niversity college of engineering, osmaina university.
Kindly take strict action against him as the students don't have any freedom to speak the facts before him
