Mobile does not want to turn on !!

Hi guys! I have a new Samsung Galaxy S6 Edge SM-G925F . It’s been with me for a week now and I’ve always took good care of it. No water damage, it wasn’t dropped or something. 3 hours ago , it turned off on its own and when I tried to turn it on, nothing happened. I’m freaking out now because I don’t know what to do so if you could just help me with it, I would surely appreciate it.
