Ecom Express — Product not delivered || Tracking number[protected]

Address:	Bangalore, Karnataka, 560043
Website:	Styletag

Tracking number[protected] is marked delivered without delivering the product. On Nov 11, I only received the message that "shipment is undelivered after 1st attempt", after this the tracking details shows as delivered but there was not even a single attempt made contacting me or even a delivered notification sent. Customer service says we are not responsible for this so whom should I contact to resolve the inconvenience caused to me. Looks like the courier service has misplaced the product and simply updated as complete.

I need this to be escalated further, need the product to be delivered or amount refunded.
