Nykaa.com — Haven't received my product

Placed an order on August 13th, 2021 I was supposed to receive all my orders on August 17th, 2021. The status of my order said, "out for delivery" but no one contacted me and around 9pm I received a text message saying "we couldn't deliver your products." But no one tried to contact me in the first place when I called the courier service they ask for pin then they ask for registred phone number but after I entered the registered phone number they say it's not registered and then it automatically hangs up.
