Swiggy — refund problems

Address:

IIT (BHU), Varanasi, Uttar Pradesh, 221005

Order was made on 8th july of amount rs 560 but the food was not good so the swiggy initiated a refund. But now it's 20th july and the amount hasn't reflected in my bank account till yet. They say they have refunded the amount but no progress has been made till now. They usually say the amount gets back to the credit source in 4-5 days but i'm helpless now...
