Gift codes to unlock 🔓 keyboards

About a year ago I asked SwiftKey to PLEASE send me the codes for all of the gift box codes (you guys used to give out and then stopped) And they DID! TWENTY CODES. I copy and pasted them into my secure Notebook on my phone but for some reason they are gone now. Can I please have them back? I have been with you guys a long long time Thank you ♥️ !
