Bangalore University — Im complaining about my exam fee refund which was failed as promised in the site of fee payment

I had payed my fee and it was failed . I did it again another time as it was promised to be refunded . I emailed and messaged to the authorities as given in the site but there was no minimum response at all . This is really very inappropriate and disappointing. I had payed my fee that should be refunded on 2 September 2021 its been 15 days but they had promised in the site that the amount will be refunded within 7 to 10 days . Taking this as a serious note i need my money refunded back .
