Myntra.com — wrong product return

Address: Jodhpur, Rajasthan, 342008

I’m krishna devnath. My order no. Is[protected]-9711301. I ordered an roadster shirt but instead of that i received an baby pyjama in the package. So i requested the return mentioning wrong product as a reason, but the collecting guy denied to accept the product and told me to. Call myntra for help. Which i tried but didn’t but there is no proper response to my problems. Please help me and take this product and refund my money back.
