I had my MacBook Pro 13" 3 times repaired for display issues. First time the screen had a weird white aura right in the middle of the screen under white background. The Genius guy said it was a physical damage but they will make a one time exception and the changed the whole top case. When i got back my computer i realized they had installed a used top case with one dead pixel on the screen. So i took it back and they replaced the top case again this time around with a brand spanking new one which seemed fine. A couple of months later i noticed a white blotch on the left bottom corner of my screen under white background. I took it to Apple and they changed the top lid again. This was the 3rd time they replaced the top case. I just wanted to know am i eligible for a replacement since the computer was repaired 3 times for the same problem? And if I am how do i claim it?
