Myntra is showing that the item i ordered was deliver on 27/09/2019 but i never received the product. At that time my phone was switched off and no one was at home, so when i disputed the same with myntra they assured me that they will investigate and then get back to me. Next day, a delivery agent comes to my door and confirms if i raised the dispute and informs me that he was the same agent who delivered the product. When i asked him where did he deliver he informed that, '"mam it was too dark and i was in a hurry so i am not sure which house i delivered to." so, i informed the same to myntra and then i receive an email from them that because after the product was delivered an email was sent to me as a confirmation that means the product has been delivered to me and they won't be able to do anything else. That particular delivery confirmation is what i was disputing and according to them it is a proof that i received the product. So now they are saying that as i do not agree with this they would investigate but they do not have any investigation procedure and i am losing money because of them as it was not a cheap product. I don't trust that they would do anything anymore
