To everyone's questions:
Standard donation to the WTS: "suggested" donation. It is supposed to be the elders (for the circuit) that make the motion and second it as to the amount. I'm sure the CO/DO have their little opinions. A lot of it depends on the past record of the circuit's ability to pay. I don't know what happens if their expectations are not matched by the donations. I do know that the WTS gets their money first and any money for the maintenance fund or expenses has to be made up by the circuit in another way.
As far as I know, the elders are not consulted at the district level, so I imagine that the CO(s) assigned to that DC and the DO, make the decision.
They take into account the number of publishers in each circuit and determine the "suggested" donation much like how the WTS handled the auto/health insurance for the CO/DO in the past.
Have you ever noticed there there is never a breakdown of the expenses like there is in the congregation once a month?
Has the Society lied to you?: That's a rhetorical question, right? Actually, you aren't entitled to know, so according to the WTS defnition of lying, they were telling you the truth.
What would happen if you questioned the CO's expenses? You would be marked as a complainer and it would take ten years of good behavior to get the mark removed. Moving and changing your name might be a good idea.
