Pantaloons Fashion & Retail — People Blue Jeans(size-32) (price-1299)

I had ordered a People Blue Jeans(size-32) price 1299 from pantaloons on date 22 may 2021 and it got delivered on 27 may 2021. when I opened the pakage it had leggings priced only199. which was way different than what I ordered. even after multiple complaints theirs courier partner does not pick up the return because pantaloons is not nit telling them the reson that I had a different product to return which i received in place of jeans. this is becoming so much frustrating. please give a solution.
