Myntra.com — Product getting rejected

This is for the second time they are rejecting the product when in the first place they sent me a defected product . When I had ordered shoes for the first time there was already a mark present on it and when I complained about the same they told that the black mark was not present when we delivered it . That issue never got resolved.

Now when I ordered a kurta set, the quality of the material was extremely low and there were marks on it . They have successfully again rejected to take it back claiming it doesn't pass their quality check . What do they even mean by quality check . Spending hours on customer service they just come with saying ma'am we cannot do anything. What is the use of delivering the product so fast when you cannot give a good service .
