Apple Care Customer service rep.- Alex
I tried today to upgrade to Mountain Lion -made the MISTAKE of calling Customer Support(paid for 2015) and ended up with ALEX-Apple Customer Care Rep. She tells me to go to the UpToDate.apple.com website and read it.I had to PAY/buy Mountain Lion. Explaining over and over I purchased it afterJune 11,2012 as YOUR RECORDS show ,she said I DO NOT WANT TO ARGUE with you. At which point I ended the Call.
Be ware of Alex as Customer Service Apple Care Rep
Even though I paid for the EXTENDED Apple Care (2015) one would "try and try again" until they get their money's worth.
