Myntra.com — I want to return my product but the status is showing Delivery Delayed

I had ordered Reebok Shoes from Myntra on 17th June 2023 and received the product on 19th June 2023 at 2:30 pm. I want to return the product as it’s not comfortable at all but I have no option on Myntra App as the status shown on the app says delivery delayed. I have called customer care several times but they seem to be least bothered about the issue. The delivery was done through M Express which is Myntras own courier service which claims 48 hours delivery. Every time I raise a complaint it is closed and mentioned as Issue resolved. This is wrong business tactics by Myntra.
