burn mark on magsafe pins

this is when it started, i cleaned (very well) both ends with iso prop alchool and left it to dry for 10 minutes, but it still became burnt after.

using 30w apple charger and magsafe cable. cable is also burnt but less noticeble.

should i deal with this or return and get a different one. using usb c so i dont start a fire or something.

i searched google but only found issues about magsafe 1 and 2, none about 3

this is a 2 week old laptop, wtf is this
