Hello there, Thank you very much for reaching out to us. I'm sorry to hear that you are having issues claiming your rewards for completing the campaign on Legendary on your Warlock. To rule out any issues that may be occurring with the game files, can you try clearing your console's game cache to see if it helps? I've included a link to help if needed. If you are still missing the items, can you double-check at the Cantina to ensure there's no additional dialogue you may need to go through to get the gear? Please also double-check the Postmaster, in case it may have ended up there somehow.
