Pizza Hut India — Money debited but order not placed and no refund received yet

I recently made an order in pizza hut but my order wasn't done but the money was successfully sent to the pizzahut, so I went to my nearest pizzahut where I had a chat with the staff about my problem and they said I'll receive the refund within 24 hours, it's been 3 days since that day but I haven't received any of my refund. I've tried contacting them but they don't seem to help me out and they keep neglecting me and doesn't help me with my refund.
