Myntra.com — Product not delivered but payment taken

I made multiple orders with Myntra worth more than 15k. On Saturday 7th May they delivered many products and the package was in bulk as they dump all products in one cover. Again cheap way for Myntra to make it cost effective for themselves plus cheat customers. The delivery guy takes the money first then give the bags and leave. He has no clue what is in the packet. When i open i see a few shirts and pant and then i check my app they have claimed a deodorant worth 1600 is delivered. Carolina Herrera deodorant. I raise a complaint via app IN[protected] and they ask me if the package was tampered. I was honest and said i dont recall it to be tampered. Then they say their security check claims it was delivered so they can't help me. How cheap is that? So if had lied to them that the package was tampered then they would've given me a refund? The escalation guy who i called put me on hold for 2 mins and then he says he completed his investigation and the product was delivered. He did investigation in 2 mins? When i ask him what investigation he did there is no answer but he keeps repeating he cannot help with my claim. I need a solution for this please help
