MacBook Pro Support - Please Help
My MacBook Pro has been in repairs for past one and half years. The problem is continuous freezing, pink and blue screen, garbled screen. Tech Center have already changed the Logic board 4 times, Keyboard, speakers, top & bottom casing, battery and optical drive over the course of 1year. The last repair was about a month ago where they again replaced the Logic board, and now the problems have started again - Freezing, Pink/blue screen flashing while watching videos online, Speed decreases (everything literally working in slow-mo), fan is mostly running at its top speed, and all this happens when only one or two browser windows open without any extensive process running on it. Also, it has been formatted multiple times over past year. Every time I contact support they go through the same process again and again. Please let me know if there is any way I can contact higher management to find a resolution, I am really frustrated and tired with the product and process. Any help would be appreciated.
