Want to swap out Heirlooms.

I usually don't go to the extent of the WoW forums for help with this, and I don't like to QQ, but here is my problem:

I bought a Heirloom Shoulder, Chestpiece, and Bow for a hunter. I leveled him to 41, and it got pretty boring, so I decided to try a different class. Later that day, I went over to my friend's house, and he had a level 80 mage- so I tried it, and it was really fun. Iv'e been trying to get the items refunded (Yes, maybe I am an idiot for doing that). My point is, I want to level a mage with some heirlooms, but I can't even swap them out. With my Test Prep coming up in school, I really don't have that much time to grind emblems, and it would probably take months to get enough emblems for the Tattered Dreadmist set and the Dignified Headmaster's Charge.

I have made 2 GM tickets, one asking to refund the emblems, and another one asking to swap them out for the cloth ones....both got declined /cry. I won't quit WoW over this problem, but I really don't like grinding emblems on my 80 DK. I doubt there is a solution to this problem, and maybe there is some hope to getting these heirlooms swapped out. Hell, I would even delete my hunter and give away all my gold if I had to.

So, is there any way I can resolve this, or am I screwed?

Thanks,
Kenjan.
