давай саппорт ответит, а там и решим)

Hello Mihey3Z.
I've added the ticket to the supermod queue to have a single copy removed from the giveaway. We are currently experiencing a shortage of users capable of handling this kind of ticket so we appreciate your patience in this matter.
Thank you for the ticket and also for the generosity in agreeing to their request.
Have a good day!

типа нужно подождать, ибо супермод самый могучий, а мы не можем.

Так что ждем
Спросил, можно ли удалить все три копии

Thanks ^^
I can't delete whole giveaway (all 3 copies) without all winners permission?
One of the winners permabanned, another not active on steamgifts for 10 months
