I purchase designer dress through marketplace facebook, but the item was inappropriate in terms of quality and size. I contacted the guy through messenger, he was not responding. No response from him since then. Then i contacted the owner, but ultimately no response. Please help me in retuning the item, and refund for the same.
Ps - attached is the conversation with owner - with his mob num.
