Myntra.com — Myntra not giving me refund

I ordered a product from myntra and returned it as it didn't fit me. I made sure i return it with all the tags and bills. After waiting for almost 7 days they rejected my refund saying that the tags were not in the product which was a lie. later they said i'll be reshipped my product with 7 days but didn't receive it either. it took 10 days to get my parcel. in which in got a wrong product. raised it to myntra many times they just keep giving me timelines and they is no update on my case. their customer service is least botherd and no one from their team has called or given me assurance that it would be resolved. no update on what is the solution.
