Meesho — Not returning wrong product

I have bought a saree from Meesho but the product delivered to me is completely different and of low quality. I have tried to return it thrice but everytime delivery boy denies to take it and cancel my return. Even the customer care services are ver poor and they are straight away denying to help me out with my problem. According to them the product delivered is correct. They even misbehaved when I asked them to divert my call to higher authorities, they put my call on hold for 30 minutes and sometimes they hang up in between.
