update: I went to best buy because they agreed to fix/ replace my laptop if i show them the charger i used. So I bring my charger in and they tell me to take my laptop to apple directly and deal with them. I asked them why i paid an extra 300 for the extended warranty from them if theyre just going to screw me over and send me to apple. They basically said the first year of the warranty, apple fixes everything. Then after the first year, its us who you deal with.
Im so fed up, i dont know wtf to do at this point. When I start up the laptop it works perfectly. But if you look at the side you can see the burnt part. I dont want to take the laptop back home and then have complications later on.
I told them to ship it to apple for me with the charger and ask them to check it out again. they basically told me that they will do that but if apple denys the warranty, im shit out of luck.
