Bigbasket.com — order status! missing

Address:	Hyderabad, Andhra Pradesh, 500032
Website:	bigbasket.com

I ordered 5 items today morning (around 8:30 AM), "In Express" and this is what happened:

When no one delivered it till 1, I checked the app and it said 'order status as delivered'. but I had not received the order.

I called customer service and they said they will escalate and call me in 15 mins to update the status - No delivery, and no on called again!

I pinged on customer care chat window at 2 PM and 3 customer service reps pinged me for details and did not get back to me:
1. Soujanya S.
2. Lakshmikanth S.
3. S Parahana

All of them said they will escalate the issue and when I asked to cancel, they closed the chat window.

There is still no delivery or even response from BigBasket.
