So we the new update the challenge a friend quest was updated … It still states that you “both” get rewards, but only him got the XP , while I got no gold no nothing.
What’s the point of a quest for friends if you get nothing ?
as far as I know the player who gets that quest must be the one who needs to invate his friend first…
everything else I don’t know,try to contact support
Lol, if it is not a bug or lordglog siad then it shows blizzards priority’s in decision making.
How can you contact customer support outside forums ?
Send a letter to one of the CEO’s to their headquartes… or his home 
Or it is indeed about money 
go on official blizzardb site,login into your acc and you will see “support” then you pick hearthstone below and than you contact support and open ticket…everything you need to know is there,you just need to read
