Invincible's Reins Mislooted By GMs

I need some clarification and perhaps some action on this issue. It involves a former member of our guild that somehow managed to get Invincible's Reins from a GM under false pretenses. Here is the situation:

Approximately two weeks ago, we killed Lich King in 25-man on Heroic difficulty. 2x284 weapons, a Shadowfrost Shard, and Invincible's Reins drop. Our loot master, who is also our guild master (will be referred to as Person A), disconnects during loot handling and is not able to log back on for some reason. The weapons got looted before the disconnect, but the Shadowfrost Shard and Invincible's Reins were still on the Lich King's corpse when we all left. We had decided too who these items were going to. The Shadowfrost Shard was going to go to Person B and the Reins would go to Person C.

Person A contacts a GM about getting the two items left sent to their respective recipients. However, the GM sends both the items to Person A. Person A cannot use a Shadowfrost Shard since they are not a plate-wearing class nor did they want Invincible's Reins. A second ticket was submitted.

At the same time, Person C submits a ticket asking that Invincible's Reins be looted to him. The GM responding to Person C turns down their request because apparently only the master looter or the person with the looted item (both of which is still Person A) is able to get that type of request accommodated.

Person D takes up some drama with Person A about not getting to raid enough and demands Invincible's Reins or they're going to pull their spouse out who is one of our core raiders. After some conversation, Person D takes it upon themselves to submit a parallel ticket to a GM playing some sort of victim complex and requesting that Invincible's Reins be looted to him.

Today, we find out that the Shadowfrost Shard intended for Person B was successfully sent to Person B. However, the Invincible's Reins was not received by Person C and instead went to Person D who posted the deceptive ticket. Person D uses the item to get the feat and the spell and subsequently gets kicked from the guild. So the GM answering Person D's ticket saw no problem with just handing him the mount DESPITE THE FACT that a GM previously answered Person C with an opposite response.

Person A has contacted a GM one more time to try to alleviate this issue, and we were told what was told to Person C. Only the person with the looted item can make the decision of where it goes... There were no loot rules set ahead of time for this person to go back on and make claims about; It was a straight 1-25 roll for the reins and Person C won it fair and square.

So our own loot master gets blocked by a GM and so does the person this mount was intended for... but for some reason someone else was accommodated and looted Invincible's Reins without question and without the standard denial. This is a huge inconvenience and obviously a double standard.

I'd like to know why Person D was able to get Invincible's Reins without the hassle, and I, amongst others in my guild, would like to see this remedied.

I have the name of the GM in question who gave Person D the mount, so feel free to contact me in-game on any of my characters if you investigate this.

Edit: That's cute. Topic gets locked thanks to a bunch of speculative idiots who ironically accuse my testimony of being 'speculation'. If I wanted your community college-level psych evaluations, I'd ask for them.
