Samsung — Samsung technician Subhash Lohar

On 25th May I purchased a Samsung refrigerator from Amazon. It was completely fine but during the installation of the refrigerator the Samsung technician Subhash Lohar broke the moveable ice maker. I've contacted the Samsung product support and suddenly he's claiming that he didn't broke the ice maker but it was broken from earlier. It was an open box delivery so we thoroughly checked the product to be sure that there's no problem in the refrigerator. He's completely lying and refusing to give a new one or refund.
