Maxbhi / Elcotek Telecom — Cheaters maxbhi.com not working product delivery details

I am Divakar murthy, m:[protected] & booked a One plus 2 mobile display at maxbhi.com. The received One plus 2 mobile display LCD light in the display screen is not working. When it is fit to the phone, the phone switch's on by vibrating. No display is visible and the screen remains black. So I requested a replacement as per warranty valid till dec 1. They asked for photographs of the new display they sent, plus my mobile photo. I sent them all. Now they say as the warranty sticker is removed so they don't replace it. There was no sticker on the product & I have not removed anything & the product is kept as received on arrival. maxbhi.com is cheating by sending damaged products & no replacement also.
Concerned authority please help me return or refund this damaged mobile display
