Flipkart — Warranty Related

I bought so many products from flipkart. I faced no issues but last few orders disappointed and littrely harassed me.
Again I faced harassment from flipkart. I ordered hisense A6GE 50 inch tv from flipkart and when I was ordering the product, it was showing that I will get 2 years comprehensive hisense warranty. But when product got delivered ( product was open box delivery) I saw one year warranty card. When I ordered the tv it has 2 years comprehensive warranty. Now it's changed to 1 year. But it has 2 years and it was showing the warranty for two days not for two hours.
I called the customer care. They denied the warranty. I talked with the senior of customer executive. they also denied the warranty and said now showing 1 years warranty so you will get 1 year warranty.
I argued about it then they said I'm taking the note about it. wait for it.
This is littrely harassment. I couldn't imagine flipkart will scam with me like this. Totally unexpected. I want solution about this issue or please return the product. I don't want the product anymore.
