Nykaa — nykaa lipstick matte collection set

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I have ordered three items on 14th of aug'19 and received on 22nd of aug'19, only two items in a box. I raise a complaint, nykaa is saying that their team investigated and found that all product has been delivered, but i received only two product and third one is missing which is of rs. 5399.
I am calling them again and again they are simply saying sorry and saying we can't provide any resolution.
Previously also i ordered from nykaa, no doubt product is of best quality but before also there was a missing of item and defected item came even they provide resolution also but that was not of much amount.
