Zivame — i want to return both products and want refund

Website:

Zivame.com

I bought 2 products from zivame.com
And i want to return those products and want refund. But the site shows that product has not yet been delivered so j am not able to initiate q return request through the app, i tried to call them and emailed them even tweeted on twitter multiple times, but no response from their side
The products are not at all good
They have been very insensitive towards me as a customer, i am highly disappointed
Please help me with the same
