Nykaa.com — Regarding undeliverable products

I placed 2 orders as pink Friday sell is going on. Both of my orders got canceled and returned to the warehouse. If those orders were not deliverable to particular address then Insted canceling the order customer should get some notification
This is really very disappointing and irritating thing
I also made an contact with customer support and got response that something issue is with courier partners and they returned the products to warehouse.
