Not charging I suppose?

Greetings,

I bought a 2nd hand MacBook Pro 13" Touch Bar Late 2016 . I get 7 minutes to test the device before payment on delivery, so I checked for everything. Worked awesome. After using it for an hour, the laptop turned off, since it didn’t had power. The seller forgot to send the usb-c cable, so I had only the power supply. After a week I managed to buy an original usb-c cable for macbooks from a licensed apple reseller. I tried charging the laptop, first it wasn’t charging and when I tried to switch it on it only showed that I must put it to charge. I tried charging it again, but this time the laptop didn’t turn at all. A day has passed, it’s the same. I contacted the seller (he sells macbooks 2nd hand, refurbished & new), we agreed I will send him the laptop to check it, try with another charger to see if the problem is cause of it. I am worried because it might burned because after the 2nd attempt to charge it, it wasn’t even showing that it doesn’t got battery.
