Tata Cliq — product not delivered

Website:

tata cliq

I have placed a prepaid order on the tata cliq app on 23rd april 2019.
I got a delivery call on 25th april but i coudn't pick it up from my office (Delivery address) that day because i wasn't well.
So i told the person to deliver it the next day i. E 26th april and he agreed to do that.
Since then, i haven't got any call for the product delivery instead i got a message on 26th that i have cancelled the order when i haven't actually done it.

So the same day, i called the tata cliq customer support to look into this issue.
They assured me that the order has not been cancelled and it will be delivered to me in the next 2 days.
Till now i havent got my product nor any call from tata cliq.
Today, when i called the customer support, they told me that the product is out for delivery and it will be delivered by 7 pm.
I havent got my product till now.
Please help me to cancel this order and get my money back.
