Help, something feels off with 70-742
First off all, thank everyone for their contributions to this forum.  It has been a great asset to me.
But I am in dire need of some assistance and would appreciate any feedback that anyone can give.  I am in the process of attaining my MCSA for Windows Server 2016.  I earned my MCSA for Windows 10 at the end of 2016.
I have been working my butt off and I passed the 70-740 and 70-741 exams in August and October and passed the first time on each, as well as I passed the 70-697 and 70-698 in 2016 the first time on each.
However, here is my issue.  I failed the 70-742 exam in November with a score of 616.  No big deal, I thought, as I purchased an exam replay and got an extra retake.  I took it a week later again I failed, again, this time with a score of 666.
I was very frustrated, but figured, hey, I improved.  So I studied more (I have read 2 books, watched 35 hours of video on ITProTV, taken countless Transcender Practice exams, used flash cards, watched even more video and power point presentations I have found online, etc since October) Not to mention, I am a Systems Admin and Network Engineer for a managed service provider.  I took the exam in December and failed again.  The odd part, I got the same score of 666.  Strange, but chalked it up to coincidence.
So I picked my self up, dusted myself off, and went back to studying.  I went in today and took the exam again.  I was very confident in my answers and felt really good about the exam.  I went through each question 4 times before I clicked the finish button.  Happy with my answers, I clicked finish.  An yet again, I was met with a "failed" message with as score of... you guessed it, 666.
So if you are keeping count, the last 3 times I took this exam, I have scored a 666/1000.  Something just doesn't feel right, and if the scores were different failing scores each time, I don't think I would have given it any more thought.  But I know this content, and work with it every day.  I find it difficult to accept that I have failed 3 times with the exact same score.  Almost like something is wrong with the application and a score above 666 cannot be attained.    Has anyone ever run into this before, is there an appeals process with Microsoft so I can have them check into this?  Any input from this community would be greatly appreciated.
