Flipkart — Product not delivered from nearest hub

I placed an order for Google 8 Pro phone on 8th Oct and the promised delivery date was 14th Oct. :ater it was changed to 16th and from 16th it was again updated to 21 Oct. I have cancelled the order and placed one more order.

Actual promised delivery date is 19th Oct and now they say its updated to 21st Oct.

When I contacted the customer care, the associate hang the phone on me but they dont give any proper response.
