Do Apple have a complaints department? I ask because I bought my nMP in March of this year and received it in April. Since it arrived I've had a ton of issues. From display glitches and lag, to storage problems, drastically slower transfer speeds over USB3 and Ethernet and more recently, problems with Mac applications, specifically Messages. I've spent the good part of the last three and a half weeks on the phone to AppleCare technical support. I've had technicians control my screen remotely, I've sent across half a dozen console logs and even screen recordings to Apple's engineers to look into. After maybe the 12th phone appointment with an AppleCare representative, my calls were eventually moved up to customer relations where they started discussing replacing the machine. After a lot of back-and-forth and scheduled callbacks (some of which I never received). Get this, one rep reportedly called me on Friday at 7:10PM and left a voicemail. Not only didn't I receive a call, but I don't have voicemail setup on that phone. I eventually did receive a callback and the conversations seemed to regress from a replacement being arranged, to a Genius Bar appointment being scheduled to (as of today) me being advised to continue speaking to AppleCare over the telephone. As you might imagine, one begins to get exhausted of talking to Apple reps. It's gotten so bad I know their hold music arrangement off by heart (Is This Love, Under The Boardwalk, Ring of Fire, Tighten Up etc). With this Mac Pro being my sole work machine, taking into a Genius Bar for X amount of days isn't a viable option. I've also given up hope that Apple can help me over the phone. I'm not entirely sure how I went from tech support, to a replacement being looked into, then back to tech support. I've tried to be patient with the process, but my patience is beginning to wear thin. After speaking to a long line of Apple reps in various departments, I wanted to know if there's a department where I can make a formal complaint about how my case has been handled. I'm far from happy with the solution that's being offered, I'm essentially back where I started and I'd like for someone at Apple to look into this. Anyone had any previous experience with Apple? After owning Apple products for the past 10 years, this is the first time I've ran into a problem and it's been taxing. Any help or advice is appreciated.
