Hearthstone - perks stopped working

I paid in gold for the perks for battlegrounds, and it worked fine for awhile, but the last day, it only gives me 2 heroes to chose from. When I click on perks, it says that I paid for them. What is going on? Either refund me the gold, or fix the issue.

You have to use up your arena tickets. Then pay 2500 gold or 19.95 for new set of perks and arena tickets. Which sucks if you don’t play arena. I just created a deck and retired it 4 times. Would be nice if Blizz would offer the perks seperately at a reduced price for those of us who don’t play arena.
