Comptia revoked my cert.

I recently recieved a letter stating "statistical anomalies" were detected in my test. That's it zero clarification. After explaining that I have years of network experience and studied for months they chose to uphold the revocation. I am disgusted with this. What a waste of money. I passed with an 850 out of 900. What's the point of getting certs if they can be revoked with zero evidence?

Update: I just sent 32 pages of proof to comptias security team with proof of completed courses, hand written notes, study times,and test scores. We shall see what happens next
