Myntra.com — Not allowing exchange of product

Address:

1007 MAK Lifestyle Apartments, Vidyanagar, Kasaragod, 671123

I ordered a pair of sandals from myntra for which I'm eligible for exchange by 7/08/2023. Today is just 5/08/2023 and they are not processing my request. In fact my number has even been barred from making calls to their customer care. This is a real serious issue. I don't know how many people are facing similar issues. I have a right to exchange the product (tag and everything intact) if it isn't what I'm looking for. They even charge a processing for all the purchases I make. Which mean they are liable to service my request. If it doesn't get processed in a day, I will definitely file a suit against myntra.
