Myntra.com — negligence and constant denial of service

I ordered 2 shirts (Locomotive brand size 40 and 42) for my brother's wedding from myntra on 8th april. They delivered the products on 14th april. To my surprise i received a jean instead of 42 size shirt. I intimated this to myntra. But unfortunately the response from myntra was not satisfactory. They are not ready to replace or refund for a mistake from their end. The customer care people was rude and constantly neglecting my request. Because of lack o[censored]pdates from myntra the delivery person was not ready to pick up the wrong product. After long discussion delivery person took the shirt which is low quality cheap product today but the wrong product pick up is still pending.
