Blizz, please help me fix my stupid mistake

Yes, I made a very stupid mistake, you can all laugh at me.

I'm not in a raiding guild, so I have to rely on PUGs to do ICC25 runs. So I don't have a lot of opportunities to get protectors marks. Tonight, I finally got one - YAY. and having the frost in hand, I wen to get my Sanctified Ymirjar shoulders. Yep, you guess ed - I bought the wrong ones - I'm fury spec, I meant to buy the Shoulderplates, but bought the Pauldrons instead. OK, not a total disaster - right? Nope, I gemmed & enchanted them BEFORE realizing I had the wrong ones....

*SIGH*

Okay, you can all make fun of me now...

Is there any way a kindly Blizz GM can either swap these for me, or give me a refund anyway? I don't care if I have to re-gem & re-enchant - I'll call that the price of stupidity.

They are in my backpack. Thanks for the help.
