Samsung Smart TV - No assistance

During the year 2019, I purchased a Samsung Smart TV 49", the TV currently reflects a shadow like image, The original slip was kept but faded over time, I had attempted to contact the Gateway branch multiple times, but have not received any response as yet. I would like to be assisted with regards to having the TV inspected and repaired. Please refer to emails which contain confidential information such as ID numbers in order to trace the purchase at the Gateway store and assist. Thank You
