Accidental purchase
Unfortunately not at this time. No
not very likely. Especially atm when customer service is so spread thin. Warcraft made exceptions to badge purchased items but not gold.
I wouldn’t submit a ticket for this. There’s no way you get a reversal or anything like that on this issue. ATM there’s no “grace period” or “buy back” vendor option. I know it sucks man, sorry but I would just chalk it up to “stuff happens”. Sorry again for your loss.
