Dogman, I can explain what has happened here...
They simply had your FAST test marked by the same incompete... ah, people who screw up Flight Crew Licencing exams on a regular basis. Perhaps you could pay an exhorbitant fee for them to correct their error.
And BTW, sorry to hear you had to learn the hard way. Never, NEVER tell the CAA (refer other thread for the missing "S") anything. Yes, an awesome culture to cultivate between pilots and the regulator - but you simply don't have a choice with the way they behave.
Next thing you know, if you answer "monthly" to the question "how often do you watch TV shows featuring criminal activity" then you'll be on a watch list for your ASIC.
