[Resolved]  Samsung — Defective product received

Hi! I ordered Samsung Galaxy Tab S7+ from Samsung E Shop on 24th Feb and got it delivered on 26th Feb. I have Green tint issue on the tablet as samsung have this issue since the launch of the tablet. In green tint issue, when I lower the brightness, then the grey objects appear to be green. But, samsung doesn't take any action to fix these issues and doubled their promotion of the tab with some offers. I went to the service center, then the first service centre don't know "What is Green Tint Issue?" They didn't understand the problem. After that, I lodged complaint against them and went to the another service center. They checked and got the issue correctly. But, they said that "This is not a issue. It's a feature". My friend have same tablet and he don't have such kind of issue. So, they denied my claim and said if we will replace the product, samsung would charge fine on them. I also lodged complaint on customer care but, they only want me to visit the service center and check the device again and again, so that the DOA period will over and, then they will free from the issue. So, I request you to please help me to get my money back. This is the common problem in almost all the panels of the tablet and latest smartphones of Samsung. I am attaching some pics of the issue. Kindly help me.
