Bl TPS PS3 Shift codes not working

I cant figure it out guys…I keep putting in the code, then there is a long delay and it keeps saying active codes cant be redeemed…Did i use too many codes already or something?

Active or Inactive codes? Sounds like a job for support: https://gearboxsoftware.zendesk.com/hc/en-us

Active codes

Thanks bud!
