Meesho — Complaining about cancelled order delivered

I ordered jwellery product of 1065 rupees from meesho and cancelled next day but after three days I got product delivered and paid the amount as it was cash on delivery from bluedart. And when I checked the product it's a saree not even worth. I wanted to return the product but unable to because I already cancelled in meesho. If I contact meesho they are saying that there is no way to return as it already cancelled, if it's already cancelled then how the product got delivered. And meesho people saying that bluedart is not their delivery partner. My question is how did I get the product with same order date and same price if it's already cancelled? Who sent this through bluedart if not meesho? Whom do I return this product? Who taken my money if not meesho and bluedart?
