All Eyes Over Here — mediator ignoring for exchange

I hv brought a gown which was totally different from the picture of the dress from the insta page posaakh. When i messaged back to her to give me address for returning the product, she gives me after sale service manager ms. Komal who is not replying nor picking up the call. After that posaakh lady started ignoring me too. This is blunder. These types of people just making the online shopping worst.
