University Of Madras — Refund the fees

As I have applied for Msc biotechnology in University of Madras, in return for that the head of the department send me a mail asking the copies o[censored]g marksheet and school certificates and 𝙧𝙚𝙘𝙚𝙞𝙥𝙩 𝙤𝙛 𝙤𝙣𝙡𝙞𝙣𝙚 𝙛𝙚𝙚𝙨 𝙥𝙖𝙮𝙢𝙚𝙣𝙩. And i have paid ₹7, 425, but now they are denied my admission and are not refunding my money.

As far I know UNOM was one of the prestigious university of India and they are behaving like this indicates the indiscipline of the Institute. Feeling ashamed to say this.
