Flipkart — Fake damaged product yet not replacing/ refunding

I ordered a la roche posay baume cream from flipkart even though it said fplus assured. i checked the contents and compared it with web to find that this cream is inauthentic and it has a weird texture and fragrance even though it says it is fragrance free (another proof of the product being fake). on top of that, it arrived in a damaged box yet they’re not agreeing on replacing or refunding. it is an f plus assured product by the way, with no expiry date or product code. very disappointed with flipkart, do not buy makeup/ skincare from flipkart if you’re reading this
