SACSmith,
If you have been wronged on your F6000 then simply use the chain of command and issue a QR1000 Redress of Complaint. If you have tried this line and failed then write to your MP who may raise a PQ in the house or he may write to the under secretary of state for defence on your behave. Visit your MP at his surgery and discuss the matter.
On the subject of Commissioning, you sound like an ok chap so you haven't got a hope in hell. Remember there is a test simply put do you have the C's or the S's in your character -
Co-operative. .Compliant. .Considerate etc
or
Self-centered. .Selfish. .Stupid. .Self-serving
If your an S man then you don't know the first thing about Honesty, Loyalty & Integrity and you are ideal commissioning material.
