Chandigarh University — Regarding the security Fees refund

Address: Punjab

I have not received my security fees after completing my Degree and after taking and submitting my NOC at the accounts office . There are no dues so why they are not refunding my security fees its been over four/4 months submitting my NOC and account details and they said at that time it will be received within 90 days that didn't happened . Kindly look into this matter and solve as quickly as possible .
