I ended up reading it, and I wanted to highlight something. That same post links to a Classic version (as the OP’s post pertains to Classic), as well, as (according to that thread) there’s some differences between the Standard game and Classic.
Please note: Policies around Classic World of Warcraft support will differ slightly. Details can be found in the post: WoW Classic Customer Support and You
Nonetheless, everyone here (except the OP) is saying the correct things. Highlighting the Classic version of what Customer Support cannot do, as my prior quote already links to the Classic Version:
Customer Support will be unable to:
- Restore quest items lost through deletion or quest abandonment. You’ll need to reacquire the quest and obtain the item again.
- Swap quest rewards
- Unbind items bound to a character
- Exchange bind on pick up loot between characters.
- Raid items will have a 2 hour trade window
