Myntra.com — Mango jeans refund refused

I ordered a mango jeans but unfortunately it was big in size so I requested it's return so on 1/09/2022 delivery boy picked up the article in excellent condition from my home with proper inspection and all tags intact but he called me at odd hours in night and put a false allegations that it was wet which is a great lie and you are re shipping it to me which is unacceptable because I will not suffer because of your staff negligence and he is the one who harmed the product so I want my refund back or otherwise I will have to file a petition against you in consumer court
