Gear-Fit Pro (large) malfunction

I bought a gear-fit pro Large watch at Samsung store over a year ago, 10 months into it, the watch just stopped working. I took it back to the shop (Samsung store at Mall of Africa), and assessment was made, and it turned out the was something wrong with the batter, which I then paid for, a week before level 5 lock-down. The watch also had a small scratch on the face and was told that Samsung wont honor the warranty because of it. I picked up the watch in centurion after about two months due to lock-down, and only wore it for about two to three week there after and it went blank again. I am lost, disappointed as this was a big investment for me and it is disappointing that Samsung did nothing to assist me.
