Myntra.com — Mango dress

I ordered a mango dress to gift to my sister, but she didnt liked the dress, that dress was tried twice once by my sister n once by me, within a week i returned the dress with all the tags, it was it is, but my return was put on hold, when I complained they said they will reship it to me, now its reshipped to me i want to raise a complaint that why my return was put on hold, that dress wasnt worn by anyone also the tags were same
