Myntra.com — Noise Maroon Color Fit Icon 2 Calling Smartwatch

I ordered a Top then I want to exchange with Noise watch so It put it on exchange. The delivery boy came took the Top but didn’t gave me watch and it is wrongly marked delivered successfully on the app. I talked with Myntra customer care they told me it was a glitch and they will solve the problem but atleas 4-5 times I talked with them they always give another date and today half of the month completed but my problem is not solved yet!
