My apple watch wont charged after being left uncharged for a long time (2-weeks)

Hi, ive left my apple watch uncharged for more than a week and now it wont charged. I tried resetting it and doing all the things that are already in the internet but its completely dead. Its NOT in power save mode and holding the 2 buttons no matter how long dont show the apple logo. further more it wont charge (i left it charged while i slept when i woke up its still dead)

any of you guys experienced this? what should i do?
