Anyone else having issues with receiving Shift Codes

For the past month or so, I have been adding all the active shift codes and VIP codes on the Borderlands VIP website. I have received everything from guns to skins, but when I input a shift code for golden keys; they do not show up in game. I should have over a hundred, but only 8 have shown up. I also, used some of my VIP points to buy 10 golden keys for borderlands 2 and I have not gotten them. I want to make my dude badass. Help?
