Reliance Digital — My refund is not received

I ordered one plus nord CE 3 at 18, 999 on 8th of may 2024 from reliance digital online shopping platform but I was worried about reviews so i cancelled it on same day (8th of may 2024) and its been 24 hours still no refund it is such a shame on them because amazon refund immediately in an click but this is the worst scenario I've got to deal in which your money is blocked for so long that it makes you feel broke and hopeless. So I would really want my hard earned money to be refunded immediately like how I paid them and my money was deducted in no time.
