Uttar Pradesh Technical University — Money not refunded after challenge evaluation

My name is nidhi singh and i was a student of a. K. T. U. Lucknow. This is about the year 2018 when i filed challenge evaluation for the subject "fermentation biotechnology", code-nbt601 that has cost rs 5000/-. Earlier the marks were 45 and after evaluation, it got increased to 81 but i did not get my money back even after winning the challenge (Which is a policy of the university). My roll no. Is [protected] and i have attached a document here as proof.
