XPS 15-9575 2-in-1, random shutdowns, doesn't charge

Hi, so my dell xps 15 2-in-1 is still a year old and i'm already experiencing some technical issues. I'll try to be as detailed as I can to show my point.

First there's this issue of my charger saying that it's not charging despite it being plugged in and often see the battery light flashing alternating white & orange.

Lastly, I experience random shutdown like literally black screen while using the device even though it still has a more or less full battery. 

p.s by not charging I mean when i plug it in the designated port for charging it doesn't charge at all but i can still charge it in other ports which is what I'm doing just to keep it going.

Literally disappointed actually considering that this issue started like 5-6 months after purchase and the price tag on this thing.
