Delhi University — no refund of revaluation money when marks get increased

I'm student of b.com (Hons) cbcs. I have applied for revaluation in hrm and my marks got increased. When i ask them what is the procedure for refund of revaluation money since my marks got increased, they said they don't refund any money even when the marks get increased and also added if you've problem with the system go and talk to vice chancellor o[censored]niversity. My problem is why don't they refund revaluation money, all the other varsities and colleges have this provision. They refund students money because they know it was their fault not checking paper properly. But our university torture students from both sides. What i think is, this is the another source for the university to earn extra money from students. Firstly, they don't check the paper properly which compels students to apply for revaluation and then fortunately, when marks get increased, they don't refund. There are students from low income level family as well which find it difficult to pay ₹1000 for the mistake they haven't done. So, i request the university to please pay heed to my complain. It's a humble request to make a provision for refunding of revaluation money when marks get increased.
