Flipkart Internet Private Limited - Flipkart extending delivery timelines, Delivery Agent arrogant behavior

i have ordered a product through flipkart during big billion days sale
order id - od******************

the order was placed on **th oct **** and expected delivery date was **nd oct. in the morning of **nd oct when i saw that the product delivery hasn't changed to out for delivery till now i called customer care and requested them that the product is to be given as a gift next day and its extremely important for me to get it by **nd oct. they confronted me and promised that it will be delivered on **nd oct by *pm. when i didn't got any update of delivery till * pm i again called and told them the same. they again told me to wait till *pm. the product didn't get delivered on that day and around *:** i got a message from bluedart (logistic which delivering my product) that my product is undelivered because of address issues. i escalated this to flipkart support and told them to deliver the product by **rd oct noon. i had been constantly calling support to get my product at the earliest on that day but customer care support people were just saying "sorry for the inconvenience we are looking into the matter". they filed a complaint and told me to wait till **th for the resolution. the occasion passed and i didn't got the product . i traced the product on bluedart site by provided waybill number - *********** and told flipkart customer care that product it held their location and is not getting delivered. i escalated this almost everyday to support on flipkart and even tried calling bluedart but bluedart didn't even responded and flipkart person keep telling me to wait till **.
on the evening of **th oct i got a call from bluedart as well as flipkart that product will be delivered to me on **th before **:** pm. when i didn't received any notification regarding out for delivery i again notified flipkart support that i haven't received any notification of delivery and kindly provide my delivery agent's details. this time they told me that all communication regarding delivery will be done by wishmaster i waited till * pm and when i didn't received any update on my order i called flipkart support to get update on my order they told me to wait till * as it is out for delivery. at **th oct **:** pm i got call from delivery agent that order will be delivered by tomorrow when i asked him how can you do this ,it was scheduled for delivery today he told me to file a complaint and he don't care about it .

the product is still undelivered and i have lost all hopes of getting it any time soon. this been a very worst and unpleasant experience for me. in this whole duration what i have faced -
*. careless attitude of flipkart support
*. delivering agent's reckless and arrogant behavior
*. no understanding of customer's priorities from flipkart support
*. not at all fast execution
*. suggesting me to cancel the product after waiting for so long (* days promised delivery + * days delay).
*.not keeping their promises.
*. extending timelines without informing customer.
