Pathetic service

I had order for KETCH Women Grey Ethnic Motifs Printed Kurta but I received KETCH Women Pink Ethnic Motifs Printed Kurta. So I asked for exchange which was rejected. So I put another exchange which was rejected too. Finally, I went for return which was rejected saying that they have successful when through quality check, Which I am very doubtful. But however my product was picked up before it was rejected and the product was supposed to be redelivered so I could further my request for return, which still has not happened. My matter is in process for last two months.
