I bought my son a apple computer off of Amazon in August. The first 3 days it worked. My son noticed it was getting hot. The next day computer wouldn't come on. I contacted the seller he tells me it's just a bad charger and sent another one. It works for about a month then stopped again. I contact the seller and nothing. So I call Amazon customer service and they tell me they will reach out to seller and they had a week to get back to me. The week goes by and seller of course don't get back to them so I call Amazon back they say that Amazon has denied my a to z guarantee for my refund that I can appeal the claim. So now I'm stuck with a 600 dollar broken computer that my son can't use. This was the first time I have used Amazon to buy anything and now with this I will never use Amazon again.
