I have bought a shoes from myntra of ₹3449 and recieved a different product.They approved my complaint and generated pickup 3 times but the delivery boy rejected it every time after that I am trying to return them but they are not helping me in it. I am trying to contact them complaint them about the issue but there was nothing on their part other than a 24-48 hour wait . I have to return your product. For that, give me the return option or arrange a pickup. I request that you return your product and refund my cash, and I assure you that I have not damaged or used your product. Take it back as soon as possible.
