Nykaa.com — Cheating customers and worst service

Hello,
I have ordered 7 products from nykaa and which was supposed to reach on next 3 days. After the product got delivered i was able to find only 6 products out of which one was missing so immediately i called to nykaa customer care and informed the same. Its been more than 17 days since i informed but still not they didn't respond me and they just making me to wait and delaying. The supervisor who spoke to me was very rude in behaviour and i want nykaa head to take immediate action and i need the refund.

Kindly contact me [protected]
