As i am studying in global engineering college. I am unable to study engineering and due to my family situation i am going to discontinue my course and want to join any other arts course but the management is asking ₹50, 000 to give my original certificate but i have paid my full fees in the first year so kindly help me to get my original certificate from the college.
Thanking you
Your’s faithfully,
