Nykaa.com — Product missing and this people showing their supremacy instead of solving it

I received an empty box which had no product in it. I have been calling the customer service since 26th July and till date this people have not resolved the issue! And instead of solving it all they respond is we have dispatched the product from our end we can do nothing about it! Look at their arrogance! I don’t understand that this people dispatched it but what needs to be done if we have not received it????? Where should we go??? Nykaa only knows to take orders and your money rest if you receive it don’t receive it it’s your luck! Shame on you guys. This is the third time happening with me where the product is missing! And now i will definitely talk about it everywhere!
