Hi,

Please bring your device to a Samsung Service Center to have it checked out my a technician and help resolve the issue. 

Find the nearest service center near you online, or on Samsung.com, or by calling the call center or passing by one of the Samsung brand stores.

Yes sometimes the cable
Original cable ?
Then clean the USB type c port

Try someone else's charger
