Shoppersstop.com — Not refunding my money

I have purchased a casio analog watch for rs.3865 on discount its price is 4295rs on 11/04/2025 and done the payment using hdfc debit card . I returned the product due to size issue and quality issue on 15/04/2025, there return policy stated that 10 days return process for watches after 10 days I contacted their customercare support because there was no update, since I have raised more than 15 complains and talked with there customer care executives for more than 10 times, but they are not responding me properly not even returning the money they had said that the product failed in quality check but I have proof of correct and proper watch that I received and returned that only.
