Nykaa.com — 2 out of 6 products are missing

I placed an order on nykaa for 6 products on 29 november 2019 for six products and only 4 was delivered to me on dec 3 2019. Two products are missing and after raising complaints with nykaa for the same, they say that there's no issue with the products. They have not delivered two of my products and they have charged me for it. Order no: nyk[protected].
