Myntra.com — got something else

I ordered mango navy blue culletos from myntra. I prepaid it online. I get a message that your myntra cod shipment for 3158 is out on delivery. My father took it by paying the amount. What i get is mango sandals that i didnt ask for. Website shows that my navy blue culletos are delivered. It was for 1500. So i am currently in loss of more than 4500. Your costumer service is giving no positive reply to me. I have been a loyal costumer for so many years. You cant say its my fault. I have massage stating to pay 3158 for the order. I want all my money back.
