[Resolved]  Flipkart — Incorrect AND Broken/Damaged Laptop Delivered

On 4th Nov, I purchased a HP Core i3 laptop for Rs 42, 990. Delivery took place on 5th Nov.

To my dismay, when I opened the product (within 30 minutes), I found a different brand (Lenovo) laptop, which was completely broken and damaged! It is very difficult to describe the state of the laptop, so I request you to please take a look at the attached images of the laptop that was delivered to me.
I immediately called the delivery person but he refused to come back and asked me to contact the Flipkart Support to raise the complaint.
Since then, I have contacted the Flipkart Support numerous times. Every time my replacement / refund request was getting logged, and then after a couple of days, the request was getting cancelled / rejected. This happened more than 10 times!
Then, on 20th Nov, I sent another email to the Customer Support and Grievance Officer describing the history of the issue and requesting for help. Then my return request got accepted in the system. But then, another series of events started happening.
Pickup and replacement was scheduled on 27th Nov. Delivery people came on 28th Nov, and they refused to pick up the broken laptop. They were not expecting such a broken/damaged item to be picked up. They did not deliver the new item either.
Again, I contacted the Customer Support, and they again scheduled replacement on 2nd Dec. Delivery people came and again, refused to pick up the broken item. They went back on that day as well without delivering the new item.
Again, I called Customer Support and they again scheduled the replacement on 4th Dec. But, this time, no delivery took place at all. No one came to pick up nor deliver the new one!
On 7th Dec, I got a call from the Customer Support and she sadly informed me that the Seller cannot do a replacement of the item.

I tried to the best of my ability to describe the events chronologically so it would give a clear picture to you. I am still not sure that if the Seller cannot replace the item, then what was being delivered in the last two replacement deliveries (that did not get delivered anyway).

Finally, I just wanted to let you know that I have never gone through such an experience in my life earlier. I am feeling extremely frustrated and harassed. I want a full refund of my money.
