Vivoactive 4 Touch Screen does not work

Hi, the touch screen does not work, I can only press the two side bottons but the touch screen does not work. I have tried to reset but it still doent work, Any advice? I called garmin support but instead of giving me any advice (restarting or any other idea) they told that I should throw the watch to the bin. They said you should buy the new model that we are giving you a 25% disscount. However, I found that the price they are giving me is higher than in any shop so the tried to trick me.
