Nykaa.com — not delivering on particular date and doing cash issues

Address:

Kolkata, West Bengal, 700033

I ordered 136 items on nykaa.com for marriage ceremony. It costs 76, 641 inr. They're not informing the particular date of delivery and doing late in deliver. They want to send items individually. Why should i call them many times and request them to deliver? Can't they inform the customers? Even they are showing the wrong amount. Please take step ahead for it.
