Myntra.com — wrong item delivered, no exchange available!!!

Address: Kolkata, West Bengal

I have been using myntra for the past 5 years and never faced any problems with my order. But last month i ordered a necklace, but when it was delivered, there was a hair cream inside instead! Surprisingly, the transparent package it came in, had the sticker with the necklace details and bard code. I placed a request for exchange but the delivery guy refused to collect it since the item did not match the picture of the order he had with him (Of course!) i had ordered this item during the myntra eor sale and now regret it. For some unimaginable reason, myntra does not have email support and when i tried their phone lines, i could never get through to anyone in the last 7 days!!!
If there is anyone reading this from myntra who can help me, please get in touch. Order no.:[protected]-2732301.
