Flipkart — Exchange not done by flipkart

Address:	Nagpur, Maharashtra, 440022

I ordered 2 mobiles of LYF wind 3 and flame 8 out of which flipkart gave me offer for exchange of my old device- MOTO E. i made the complete payment through card, today when the delivery boy came for delivery he rejected to take the exchange device stating that there is a slight spot on the screen and so it cannot be exchanged. If this is not acceptable to flipkart then why they offer exchange to customer to fool them and then harass them. such details were not asked while ordering. customer wait for their orders with something in mind and they hang up with such hopeless service from flipkart. My mobile is in excellent working condition and am still using it. that small black spot on screen is not restricting me from using it and any mobile expert can check it. This is second time am having problem with flipkart. Next time i will make sure that i dont shop from flipkart and will also inform my near and dear ones.
