After speaking directly to apple and being shown this repair note they posted on their website -https://www.apple.com/uk/support/macbookpro-videoissues/ I proceeded to MR sales as it is local to me. After explaining I've had the machine for 4 years and that i didn't purchase the machine directly from apple and rather a third party company I was told to leave my machine for diagnosis. a week commenced and I wasn't contacted at all my status on their website was also that my machine was still under diagnosis. I finally went to the store of my own accord to hear they had wasted my time in saying I needed to provide proof of purchase and that the information i had received from apple was wrong even tho i further provided proof of speaking to a technician out in Texas on apples website who confirmed i was still possibly covered by this repair notice. I lost a week of unnecessary earnings due to MR sales terrible service! Don't use this company!
