Old issue but... bl2 heads from poker night 2

I’ve purchased HJC for the ps4 awhile ago but, I was looking up axton’s head when I realized I’ve still not received my rewards from playing the inventory on ps3. I 100% the game and tried to download the rewards, but was never prompted for the heads… I was wondering if you guys would so graciously answer this oldie but goodie question… and… possibly… fix the problem…? It would be AWESOME to have the heads to play with on ps4. Screen shot as proof.
